Takumi hates to lose and is rather bitter in defeat. He is also easily flustered and embarrassed when he makes a mistake or when someone glazes over his declarations. He also speaks Italian. He has a particularly close bond with his younger twin brother Isami. If anyone were to insult Isami he takes it personally and will do his best to silence all critics. He can also hold intense grudges when he is wronged. Tsundere boy.
