Kuraudo Kurashiki/Relationships

Kaito Ayatsuji
Kuraudo challenged Kaito two years ago, wanting to test the strength of the famed swordsman. Although Kaito did not approve of Kuraudo's behavior, he was joyful of his challenge, getting a chance to once again fight with his all. Kaito lost the duel, being apologetic to Kuraudo for not being able to show him everything the Ayatsuji Ittou-ryuu style had. They respect each other as a swordsman.

Later, Kaito trained Kuraudo in the Ayatsuji Ittou-ryuu swordsmanship, due to the latter's request, which shows their respect to each other even more. Despite Kaito has no intention to make Kuraudo heir Ayatsuji Dojo swordsmanship, as it's just a tool for him, Kuraudo becomes his right hand and starts staying most of the time in Dojo to train along with Ayase.

Ayase has a negative view of Kuraudo, as he defeated her father and took his dojo. Ayase wished to defeat him and take back the dojo. Kuraudo, however, didn't care much about Ayase, only playing around with her. Despite still not liking Kuraudo, Ayase's view of him softened a bit, after learning that her father enjoyed Kuraudo's challenge and respected him. Later, after Kuraudo join to Ayatsuji Dojo they start to train together and Ayase despite still hating him, acknowledge his strength and although she doesn't say that loud seeing him as a friend.
