^ konkichi's announcement on the deal-
this might be a similar case to Aku No Hana when a show was announced, where there was both an anime and a live action series.
Maybe. But honestly, seeing voice actors being casted as the characters makes me think it's an anime adaptation.
Though, nothing is in specifics. I can say that since that it's going on channel 1 of Asahi TV, and looking through the stuff they air, it's mostly manga adaptations, I think they air mostly anime.
So, waiting until March 27th is gonna be a long wait sigh
