This is a retroactive comment, but if anyone is confused by her name on pages 5, 13, 14 & 16, it should be "Nishi Touko", not "Nish Toru Sakurako" which is wrong. Nishi as the family name, Touko as the given name (not Sakurako).
bruh I just abbreviated it as Sakurako Nishitoru while reading
later pages also just put Nishitoru Sakurako, I guess whichever name fits the mouth, it's passable.
