Diss Diss Discussion Free Demo Now Available on Steam Ahead of Early 2027 Release

Diss Diss Discussion now has a free playable demo on Steam. Frontwing and Bushiroad released the trial on October 6, 2026, giving players access to the opening portion of the story ahead of the full visual novel's launch in early 2027.

The story takes place at Kohnodai Academy, where student autonomy is suddenly tested when student council president Risa Sakurai proposes making school uniforms optional. One seemingly simple policy change quickly exposes competing interests, romantic feelings and increasingly elaborate arguments among the students.

Opening Movie, Steam and Visual

The Demo Opens With the School's First Major Dispute

The free demo lets players experience the beginning of the conflict at Kohnodai Academy. Risa Sakurai proposes making school uniforms optional, but the apparently straightforward policy immediately exposes very different motivations among the student body.

Vice president Ryo Hiyama opposes the idea for an especially personal reason—he wants to keep seeing the senior he admires in uniform. Meanwhile, secretary Ai Hasumi quietly has feelings for Ryo.

Debate Drives the Drama

Diss Diss Discussion draws from stage works including Naigen and Iza, Seitokai, making dialogue and conflicting arguments central to its identity.

The story later reaches the Cultural Festival and the “Content Restriction Meeting,” where class representatives must distribute assignments nobody wants. Excuses, loopholes and increasingly strained logic become part of the comedy as personal motives surface.

An Ensemble Story With Multiple Perspectives

Steam describes the game as a story told through several perspectives before its cast comes together for larger discussions and votes.

Players can ultimately influence the ending, while an optional double-window system can keep the previous line of dialogue visible alongside the current text.

Takuya Fujima Handles the Character Artwork

Takuya Fujima is responsible for character design and original art, while Hijiri Anze of Peak A Soul+ handles the background music.

The opening movie uses “Bokura no Mama de (Being Who We Are)”, performed by Hisayo Abe, with lyrics by Yoshikazu Kuwashima and composition and arrangement by Hitoshi Fujima of Elements Garden.

Why This Matters

1) Everyday school issues become the source of conflict

Uniform rules and Cultural Festival assignments become dramatic because every student enters the discussion with different priorities.

2) Its theatrical roots fit the dialogue-heavy concept

The focus on arguments and ensemble interaction naturally reflects its roots in Naigen and Iza, Seitokai.

3) Players can try the opening before the 2027 launch
