Isn’t there a Japanese saying (by which I mean I’ve seen it show up in other series) about the longer you hold on to your virginity, the more magical or powerful you become? Like a wizard to a grand mage and so on and so forth? 5000 years feels like he should have passed some milestone or requirement for evolution.
This is just a thought, but instead of "Haruhana," do you think it's read as "Shunka"? oAo Did they offer readings for the kanji? (I'm a translator, so this ended up with my full attention. TTvTT;; )
