Kousuke is the very spunky grandkid of the old man Tensuke. Kousuke is very much into net battling, and so Tensuke decides to get his own navi so that they will have something in common. Sadly for his grandfather, Kousuke finds tops very boring and "antique".

We don't learn very much about Kousuke, and his navi is never given a name. We do know however that Tensuke loves him very much, and would do anything for him. Even what he despises most: Net Battling!

Kousuke is sort of a general character, but I decided to include him anyways. :P For Tensuke's sake, I guess.
This character description was made for episodes that I have seen so far. It may be updated as more episodes become available.
