About...

Zaizen Hikaru: he's one of the members of the Shitenhouji Chuu tennis team from Osaka. In the current manga arc, he is set to play doubles 1 along with Oshitari Kenya against the Seishun Gakuen Tezuka Kunimitsu and Inui Sadaharu pair during the semifinals of Nationals.

Prince of Tennis: a fairly famous animanga; artwork by Konomi Takeshi. It's about a snarky brat named Echizen Ryoma, his tennis team, and their quest to the top. Supposedly. A lot of the rival schools steal the show though <3

In My Way: in Genius 313, when Osamu-chan puts together his team lineup for their match against Seigaku, he exclaims, "Doubles 1, KENYA AND GENIUS ZAIZEN-KUN! KENYAAA, DON'T GET IN HIS WAY, OKAY?!", to which Zaizen snarkily replies, "It's okay if you get in my way." The quote stuck, and now it's plastered onto this fanlisting.

Fanlistings: these are basically lists of fans. Fanlistings can be made for anything, from food to animals to TV shows and, in this case, characters.
