Novel Vol 7 Ch 4 (The Mystery of Yōto)
Byakuya is the hero of the chapter, and he deserves it! ( source ) Apologies for it took me this long to translate Vol 7 Ch 4 (though it is indeed a very long one, ~60 novel pages). I didn’t translate the first ~12 pages (pp 119-132) because it’s just about Aoi shopping for some baking ingredients for macaroons (she plans to make it for Takechiyo-sama and Ritsuko-san, it seems); though there is an interesting page at the start of the chapter about the “Legend of Tsubaki Shirō” from a book she obtained from the local library of sort. I started the translation from p 133 onwards because this is where the story gets meaty, with Aoi following a trail about Ōdanna-sama (and also due to my limited time). The story picks up from when Aoi finished shopping for some ingredients for her macaroons. Please refrain from posting my translations elsewhere. If you need to quote it, please acknowledge my site for the quote, because translating from Japanese hardcopy texts to English is a really hard
