Katsuya is the rhythm guitarist and also leader of the band UVERworld.
Takuya, Nobuto and himself are from the same childcare centre.

4. He wants a dog
5. He is the MC along with Takuya during live performances
6. He wrote the music of モノクローム～気付けなかったdevotion～ (monochrome ~kizukenakatta devotion~) for Takuya because he treasured that song

8. He doesn’t like leaving things to the last minute
9. He sometimes replies letters that are addressed to him

17. The word behind Katsuya in ROOTS PV is sorrow
18. Apparently, he was nicknamed Donut and Takoyakki (but he doesn’t like the latter nick).

20. He likes to cook chinese style food the most
21. He once wanted to be a pilot when he was young
22. He taught Takuya how to fold his first paper plane
