Kage is the only student within the cast to not have a talent. He himself is very open about the fact that he is a NEET and actively avoids even being known to exist. He is cocky about tiny achievements, has a short fuse, and is often treated as a joke by the other members of the game. He assumes the role of the "joke" character and has a strange quirk: he is not actually within the school. He communicates with students through a remote-controlled two-way camera on a pole with wheels. He is actually locked within an apartment stocked with rations, though he has no clue where this actually is nor the mastermind's motives for including him in the game. However, his life is on the line alongside everybody else's in trials, as nonchalant and smug as he always is.

His voice could really go in any direction. It would be interesting to see personal interpretations. Only a small amount of things stay consistent: his high volume and expressive tone.

By popular demand, the canon voice that he is most similar to is Kaito Momota.
