Ore no Shoukanjuu, Shinderu

In a magical academy for summoners, students combine impressive stores of magical energy with artful incantations to usher legends, great and small, onto the battlefield. Feil Fonaf, an eighteen-year-old farmer's son, may have had a rougher upbringing than his more affluent peers, but he's here to prove he deserves his spot at the academy as much as anyone else! And as luck would have it, his counterpart summon winds up being the legendary god-slaying beast, Pandora! ...There's just one problem. (Source: Yen Press)
