Sonosuke Izayoi (十六夜 惣之助 Izayoi Sōnosuke) is a minor character featured in Super Danganronpa 2.5: Nagito Komaeda and the Destroyer of the World.

Sonosuke was created by the Neo World Program. This copy of him was created alongside Nagito Komaeda's dream in the program.

Unlike in the real world, Sonosuke and Ruruka Ando's relationship with Seiko Kimura appears to have no flaws and they're shown being very friendly with each other. This portrayal is based on Nagito's views and thoughts.


Sonosuke is a young man with a tall, lean build. He has pale blonde hair, sharp brown eyes, light-colored skin and a serious expression.

During his high school years, Sonosuke dons the standard Hope's Peak Academy uniform under a red trench coat, as well as black boots with gray straps. It's also stated that there is a multitude of weapons hidden in his coat.

Sonosuke returned as a part of Nagito's imaginary world following his death from the Neo World Program.

On Nagito's way to school in the morning, he noticed Izayoi, Ruruka and Seiko all walking together and talking with each other happily.

They are later seen at a café near the school campus, Izayoi, Ruruka and Seiko all sitting and talking with each other as friends while enjoying refreshments.

Ruruka Ando

While Sonosuke does not directly converse with Ruruka, he is always by her side. While walking to school with her, he has a lollipop in his mouth, presumably one of Ruruka's confectioneries showing the close relationship they still share in comparison with their real-life counterparts.

Seiko Kimura

Sonosuke clearly has a friendship with Seiko, since both are with Ruruka. Despite not directly conversing, they are both seen walking to school and seated at the café together talking happily. This is the complete opposite of their real-life counterparts, as there was considerable tension amongst themselves.
