Hello everyone! This is the KAMEN RIDER toy development team.

In today's development blog, we will introduce more detailed specifications for the "CSM変身ベルト アークルver.25th," which is currently available for pre-order.


Our "ver.1," released in 2019, was very well received. As we're now releasing an updated version, we understand that some of you may be wondering what exactly has been improved and how. We hope this will answer those questions.

First
●Exterior updates
While it might be difficult to notice at a glance from the wide-angle images on the reservation page, we have made detailed changes to the sculpt in order to create the "definitive version" of ARCLE.

First, regarding how "ver.1" was created, it was based on the design data of the old series "Complete Selection" version of ARCLE, which was released 10 years earlier, and was modified by referencing photographic materials of the actual product used in the show. This time, we had the opportunity to refer to the actual prototype, so we made further changes to the design based on that.

The most noticeable change is the "connecting" section that extends from the sculpted parts on the left and right sides. We have made adjustments to the curve and depth of this section to make it even closer to the version seen in the film.



In "ver.1," this part remained unchanged from the old Complete Selection Modification (CSM) model, resulting in a pronounced curve. However, in "ver.25th," we checked the actual molded product and made corrections to reduce the degree of curvature.

In addition, "ver.1" was shorter in the depth direction, so when worn around the waist, the side buckle sections with the speakers on the left and right were positioned slightly forward of the wearer's hips. This time, this section has been redesigned and extended in the depth direction, improving the fit in terms of left and right positioning.
The "CSM ALTERING" was sculpted by taking measurements of the one used in the show, so this distance wasn't a problem, and the left and right side buckles are positioned in the same place as on the ALTERING.

In addition, we have made detailed corrections, and the section shown in the image below has been updated.

● Color update
The most noticeable change at a glance is the gold color. We've adjusted this further to make it even closer to the one used in the film. We pursued this detail when painting the weapon items in the "CSG series," and we've changed the color of this product to match that as well. When you equip both the belt and the weapon, you'll be able to appreciate how well the colors of each item match.


In addition, the silver and gunmetal colors of the ARCLE body have been slightly modified, giving it a more substantial and robust appearance.



● Updated sound effects
In "ver.1," we received praise for the high level of accuracy in reproducing the audio specifications. This time, we have added two new buttons and further enhanced the sound effects, striving to improve their quality even more.

●Transformation sounds have been re-edited and cleaned up! & Transformation sound variations have been added!
The "Mighty Form transformation sound" and "Dragon Form transformation sound" that can be heard in the publicly released product PV have been further refined from the "ver.1" transformation sound, evolving to sound almost identical to the sound in the show.



Additionally, the "Amazing Mighty Transformation Sound" has been re-edited, resulting in a more accurate reproduction of the sound from the show.

In addition, this version includes numerous transformation variations and features a gimmick that allows you to select a transformation sound by long-pressing one of the four colored buttons.

● Press and hold the blue button to transform → "EPISODE 6 Dragon Form transformation sound"
This is from the battle against Bazoo, where it took some time from pressing the button on his waist until the transformation was complete.

●Press and hold the green button to transform → "EPISODE 8 Pegasus Form transformation sound"
The sound of pressing the transformation button is the same as the green button, and the transformation sound is followed by a standby sound. Another characteristic is that the tempo of the transformation sound is longer.

● Press and hold the purple button to transform → "Episode 10 Titan Form transformation sound"
This is a short version of the transformation sound. This transformation sound can also be enjoyed in combination with the BGM standby function, which will be explained later.

● In Dragon Form, press the blue button once before attaching the Rising Armor → "Rising Dragon transformation sound from EPISODE 28"
The transformation sound has a distinctive sound that goes "Kyurukyurukyurukyuru... Bachibachi!"


In addition, it includes numerous subtle variations such as "ultra-short transformation sound (a transformation sound that's just 'kyurururu shakiin!')", "short Rising transformation sound", and "transformation sound from the normal form to a different colored Rising form", allowing for deeper gameplay even just through transformations.

The special attack sounds have also been completely revamped. We've included special attack sounds created through the development of the CSG series, and remade the special attacks for Growing, Rising Mighty, and Amazing Mighty, among other things, meticulously building everything up by re-examining the work. For Rising Mighty and Rising Titan, we've added variations to their special attack sounds, making it possible to play two different special attack sounds for each.
The explosion sounds also change depending on the special move. (In ver.1, a common explosion sound was used.)


● Newly recorded: "MASKED RIDER KUUGA Special Episode's Mighty Form transformation sound"!
The transformation scene for Mighty Form in "MASKED RIDER KUUGA Special Edition," a re-edited version of Episodes 1 and 2 of "Kuuga," had different audio than in Episode 2. This transformation sound will be newly recorded for this release.
If you press the "green button" and the "purple button" simultaneously while in the pre-transformation state, you will enter "Special Edition Mode" and be able to transform.

Furthermore, the "Mighty Form transformation sound from EPISODE 2" has also been readjusted to be even closer to the sound in the show than "ver.1". Specifically, the punch sound has been modified to be closer to the sound in the show, improving its accuracy.

● Added various sound effects
The newly added buttons allow you to play various sound effects that were not possible in "ver.1".
Also, the sound changes depending on whether it's before transformation or which form it is.

●Pre-transformation state: You can now play the "first belt wearing sound" by pressing a button.
"Version 1" played a sound when the power was turned on, but this time it can be played any number of times. However, the power-on sound has been standardized to the previous D-mode startup sound.

●Mighty Form Mode: In addition to the addition of "punch sounds" and "jump sounds," it is now possible to play sounds such as "Gouram flying in," "Gouram launching," and "Tri-Gouram sound."
After playing the "jump sound," the infrared sensor is activated to play the "landing sound." As you strike a pose in Kuuga's unique landing posture, the "smacking" sound of landing plays, making for a very satisfying NARIKIRI experience.

●Dragon Form: In addition to the "Dragon Rod striking sound" and "Dragon Rod rotation sound," this form also includes a "jumping sound." However, unlike the Mighty Form, this jumping sound is unique to the Dragon Form. Please listen and compare them.

●Pegasus Form: Similar to Mighty Form, it is now possible to play "Gouram-related sounds," and "noise caused by Pegasus's hearing" is also included. Unlike the previous button operation, it is now possible to play these sounds using a new button.
It also includes the "Grongi detection sound" and "Daguba detection sound" that were included in the CSG Pegasus Bowgun, and features a gimmick that forces it to revert to its Growing Form when it detects Daguba.

●Titan Form: You can play the "Titan Sword attack sound".

● Ultimate Form: The "fire ability sound" can now be activated using a new button instead of the transformation button. It is now possible to play the fire sound repeatedly in succession.


In addition to the above, we are currently developing various other wonderful voices. Please look forward to them!

● Equipped with a "pause sound" mode.
The "infrared sensor-activated pause sound," which was well-received in the CSM ALTERING, will also be included in the ARCLE. You can change the setting by long-pressing a new button. Those who own the ALTERING will understand the fun of this feature. Please look forward to it!

● Equipped with a "time limit" mode
- After 50 seconds in Pegasus Form, it reverts back to Growing Form.
- After 30 seconds in Rising Form, it reverts to Normal Form.
This time, we've incorporated a gimmick that recreates the setting and direction from the show, calling it a "mode."
In "ver.1," you had to set things up each time, such as long-pressing the color button to transform, but we've eliminated that hassle.


● Increased BGM and increased variety of standby gimmicks


This version includes five additional songs compared to "ver.1," allowing for even more diverse scene recreation gameplay.
The addition of opening and ending themes is not directly related to the scenes themselves, but we felt it was an essential element for a commemorative product of the work, so we added it.
"Will" is a memorable song that plays during the first battle scene of Titan Form.
"Change ~ New Form" is the song that plays when Yusuke Godai, who had died once, is resurrected and appears in his Growing Form. It was also memorable in the first appearance scene of Beat Chaser.
"EPISODE 48 Godai and Ichijo's Farewell Song" is the song that played during the scene where Godai bids farewell to Ichijo just before transforming into his Ultimate Form. (Please note that the song title listed is not the official one.) It was an important song for playing with the Ultimate Form transformation, so although it is not a song specifically for Kuuga, we were able to include it.


Furthermore, the "BGM Standby Gimmick" has also evolved. In addition to standby playback during transformation, a gimmick has been added that reproduces the BGM starting during specific scenes.
The following are some examples.

●A standby gimmick that starts the "disruption" simultaneously with the "first belt attachment sound".
● With "Growing Form Special Move Sound ③," the "transformation and kick" sequence starts immediately after the "sound of the feet glowing" plays.
● A gimmick where "Amazing Mighty Special Move Sound (second half)" starts at the same time as "Disruption (second half)".
→The sound for Amazing Mighty's special attack this time is divided into two parts: the "first half" and the "second half." After the first half finishes playing, you have to press the transformation button again to start the "second half." This allows you to prolong the silence after you and Gadol have a shootout and both of you are defeated for any length of time.

Additionally, for quieter songs, we've adjusted the start timing depending on the song so that it begins playing after the transformation sound finishes, rather than simultaneously with it.
For example, "Hero ~ Earth" is set to start playing after the transformation sound finishes, making it perfect for role-playing as Titan Form's first NARIKIRI in EPISODE 10!

In addition, the "Mighty Transformation Sound for EPISODE 2 & Special Episode" is set to start only after the transformation sound has finished playing, regardless of which background music is currently in standby mode.


●Includes two new "Mighty Anklets"!
This is the most obvious difference from "ver.1".


The sculpting and painting are quite beautiful, so I can confidently say that you'll be very satisfied when you hold it in your hands!

The CSG series has released three weapons. With the "Rising Parts" that come with them, the "Rising ARCLE Armor" included in this product, and this "Mighty Anklet," all the items from the "Rising Power Set" released in 2000 have been reborn as products aimed at adults.


●Ichijo's mobile phone also has improved voice quality!
What exactly is different about Ichijo's cell phone?
This version features improved sound quality compared to the one included with "ver.1," and includes subtle adjustments such as cutting out the slight noise present in silent sections.

That concludes our introduction to "CSM ARCLE ver.25th"! We look forward to receiving your reservations. See you soon!
