Tensuke Takumi Tensuke is the first old timer we ever meet, who actively participates in Net Battling. Not because he wants to to, of course, but rather so he'll have something in common with his dear grandson Kousuke. Tensuke's first and real passion of hobbies are his tops, which are massively collected at his home. Tensuke operates the navi Topman, which should be fairly obvious. He takes some battling lessons from Netto and his friends, so that he can impress Kousuke. Tensuke and his navi are hilarious to watch, they act just like each other. ^_^

Tensuke may seem stubborn and hot headed, but he loves his grandson very, very much.
