Before Sano confesses his love to Kenshin, he needs to get his attention and impress him, and therefore appeals to Saitou to teach him defense… but Saitou may teach him more than that.

Saitou is very irritated, for some reason, by the new development between Kenshin and Sano.
Sano knows he should be happy with Saitou, but it’s just not that simple.
What will it take to convince Saitou to allow Sano into his life?
