Sorry, not sorry, but I'm not into loli harem... All cast is 12-13 it's really weird vibe IMO, more or less each one dimensional and obviously into the MC. It's a basic "isekai go to the adventurer guild and find harem", maybe the phone could have been a good gimmick but it is just second rank as the MC has all the magic power never heard off of all element with infinite mana... Yeah who could have predicted that? I will not a elaborate on the hard because it's basic and just accentuate that all cast are the MC and the lolis. Will therefore not recommend. Maybeif had been 12 it would interest me, but which 12 year old read mange now?
