"Yojo Ihitsu," Letter
Tsuyu's letter addressed to father Kanzan reads, "Dearest father, this is Tsuyu's wish, but please don't let your health spoiled by drinking sake too much." Tsuyu made her last request to her father not to drink sake too much to weaken his health. Tsuyu called herself "Matsudaira Tsuyu" because Ikeda Family was allowed to use surname "Matsudaira." Ikeda Kanzan also sometimes called himself "Matsudaira Kanzan."
