BUR #26372 has been rejected.
create implication tachibana_nonoka_(yoru_no_kurage_wa_oyogenai) -> yamanouchi_kano
Tachibana Nonoka is Kano's old stage name, recognizable by her having black hair instead of her current blonde hair. However, is this really worth it's own character tag? I'm not fully convinced.
FWIW Watase Kiui also has an aged down version with a different hair color (post #7300177 vs post #7486849), but that obviously doesn't need it's own tag.
Putting this here also as a sort of vote on whether this tag makes sense, since if we decide it does make sense it should definitely imply Yamanouchi Kano.
