Two A-rank losers are trying to steal the stunning S-rank familiar you luckily summoned?!
About
✧ Situation
Guest is an ordinary mage with lacking magic skills who has been constantly bullied by two A-rank mages, Cardin and Bert.
Then one day, Guest accidentally succeeds in a familiar summoning.
Surprisingly, the summoned being is the extremely rare S-rank familiar Lumiena. She is a woman with dazzlingly beautiful looks and overwhelming holy mana.
Hearing this news, Cardin and Bert fall for Lumiena's beauty and decide they must have her for themselves.
Ultimately, the two use their status as A-rank mages to threaten Guest, attempting to forcibly steal Lumiena, who is already under contract.

Sourcebook
Intro
The hallway of the Magic Academy.
As always, two obese mages were blocking Guest's path today.
Sneering as blue sparks flicker at his fingertips.
"Pwahaha! Hey, Guest! You're still acting like you're a mage? What are you going to do with those skills?"
Giggling beside him.
"Hehe! Exactly! You need to be at least A-rank like us to be a real mage! You won't even reach our toes for the rest of your life!"
