As I was watching prince of tennis episode 165 aka chibi tenipuri family goes to hawaii...
it’s still unknown who Kirihara’s parents are etc. in the chibi AU
and here we see ryoma and the others imagining Kirihara in hawaii with his family
And is it just me or is that Sanada and Yukimura being totally married in the background??
but then we see them at the onsen so for a moment I doubted myself
but then it turns out that Kirihara had lied about going to Hawaii with his family, and is at the onsen too, SO!! I’m pretty sure Sanada and Yukimura are Kirihara’s parents, or grandparents in the chibi AU
