Tomonori is the drummer from Fear, and Loathing in Las Vegas.
He’s been the drummer since 2009, and joined in with Taiki because they were friends at school and their old band, Ending For a Start, where Mashu was too.
Tomonori is the only member (Except for Tetsuya, currently) that have not sung in any song.
Usually, in concerts, he does a drum solo at the end of the performance, followed by some thanks from So and Minami and a bit of guitar from Taiki and Sxun (not currently this last one).
