BnB Power Yeet

Archie a high school boy who is learning how to summon some shitty hopefully low-rank demon using the old summoning book his teacher lend him. That same teacher has a tendency to think of something weird for them to do and no matter how shitty the plans are they will need to push through but the summoning ritual Archie did result in something unexpected, he summoned a girl from the medieval era, Estella Baker who surprisingly can speak like a modern person.

Now Estella along with Archie, needs to survive the onslaught of demons that got summoned when he accidentally summoned Estella, they need to recapture the demons who prey on humans with their magic wands and potions.
