OK, this could have made a rly good manga if the characters didn't suddely lose 90 iq. It's frustrating when they are about to bust Nana but suddenly decide to not do so. Healing girl is stupid af, immortal guy is sometimes pulling 1000 iq theories and then suddenly goes in the negatives in terms of intelligence. I think the author was not ready enough and, while he had a general view of how everything would go on, didn't think enough of the details, making this frustrating and stupid. Good for a casual read, but don't expect much from this
