I like to clown on Kaisei but it's hard not to appreciate the type of rivalry he provides Akane as her "mirror", this chapter did a really good job of getting across what separates him from the others in her life
the God of Death duet is a really fun idea too. Shiguma's performance of that story is in my top 3 for pre-timeskip performances so I'm really excited to see how Akane and Kaisei put their own spins on it, especially if Both of them focus on the art of the personal for it. Also very much looking forward to Shomei's teaching methods since he seems decidedly more reasonable than Issho lol
