Kaze Hikaru, Vol. 21

After Hijikata grows suspicious of Soji's feelings about Sei, he reassigns Sei to the third troop under Saito's command. Soji, puzzled by his own recent irrational behavior toward Sei, attempts to distance himself from her. Sei, in turn, interprets this as Soji's realization of her feelings for him and decides that she can no longer serve as a bushi alongside him. She goes to visit Suigetsuni, a nun who knew Sei in her former life as a girl, to discuss renouncing the world and entering the convent!
