“If I had to choose a favorite from any of the recent Disney films, it would be Zootopia. The world-building and incorporation of contemporary themes was tremendous, and the way it presented all of that with such captivating imagery was very well done.
When I saw Idia for the first time, his dialogue had a stronger impact on me than his physical appearance. I had the thought, ‘This person…what is he even trying to say?’
When creating the role, I tried to portray a stereotypical otaku who seems to have a hard time talking to people, but suddenly becomes talkative or speaks too fast when talking about something he likes or is knowledgable or passionate about. I tried to be conscious of the atmosphere of a person with a stark difference between how they are in face-to-face situations and how they are when talking to themselves, or online: shifting from shy and reserved to suddenly swearing aloud, with an attitude.
There were several lines where I literally did not understand what the character was talking about, so I looked up what I could and asked when I couldn’t figure it out for myself. Everything else happened on the spot.
The character I like the most besides Idia is Dire Crowley. His mask is frightening, and leaves an impact on you. If I were to join one of the dormitories…I wouldn’t be moving into any dorm at this point in my life.”
-Twisted Wonderland Fanbook vol.1 (2020)
“When it was decided that I would voice Idia in the game, I didn’t know what had happened between the brothers.
But for Idia Shroud, who has difficulty talking to people face-to-face, I’m sure his younger brother is one of the few people he can truly open his heart to, and I think they acknowledge and rely on each other.”

In August 2026, the official Twisted Wonderland Twitter account published the following comments from Uchiyama on the character song/dorm song soundtrack and karaoke box implementation (source):
>> Memories from Recording
“ggwp” had sections that were so densely packed, like rap, that there was no time to breathe, so various adjustments were made during recording. Ozawa Takumi-san guided me on how to convey emotions during the recording for “Souzetsu Aeon” (双絶アイオーン), such as wanting me to put a hint of laughter into parts like “I’ve known for a hundred million years, though?” The English pronunciation guidance I received for “This Is Halloween” was extremely educational, and I was very grateful for it.
>> What should fans pay attention to in the songs you participated in?
In the “Clean Install” part of “ggwp” there is also a spoken line of “Clean Install” layered behind the singing, so I’d like fans to listen close and pick up on those kinds of little details as well. I tried the “Clean Install” line with various levels of energy during recording.
>> Which song would you like to sing at karaoke? I
’d like people to try and master the rap sections of “ggwp” in their entirety, sing “Souzetsu Aeon” as a duet, and divide up the parts and have fun while singing “This Is Halloween” together.
>> A message for the fans, please.I hope that by listening to the various songs collected together on the CD fans will be able to appreciate the distinct personalities of each dorm and the unique qualities of each character. Please enjoy both Twst’s music and game to the fullest.
