Synopsis
Mio Ubukata has begun to get used to the life of "a round trip between the academy and the" sacred place "". He will improve his fighting skills and have a natural conversation with his partymates. She had a lunch break, a lonely chat at a coffee shop ... between fights, she could also find mediocre girlish fun. Meanwhile, the party led by the genius Laila met a mighty enemy at the bottom of the "Sacred Land." The one and only "resident" who is called a "substitute" approached the strongest party of the academy with special ability and overwhelming strength.
