She's a Warlock now. Yes, and I have been informed that's the same as being a Monster's sugar baby. In other words, She summoned Sol back from the Grave alongside Kirumi, Tsumugi, Kaito, Kiibo and her father and now Sol's Soul is split between Kirumi, Kaede, Tsumugi, Shuichi and Kaito- Like, Himiko, you fucked Sol up by pouring the Cupid liquor on her soul before, and making her fall in love with Maki, Tsumugi, Tenko and Kirumi at the same time.
Half this damn plot is due to Himiko playing with metaphorical fire, even if she's the most morally clean and technically legally Clean cast member. She fuelled the Flames. And then gets the get out jail free card from Maki and Tenko. Also yes her most Canon ship is Irumeno. They are in my Canon both the cleanest characters.
Also, they have very close ages in 15 and 16, In which Himiko turns sixteen a month before the Killing game.
