Chounin A wa Akuyaku Reijou wo Doushite mo Sukuitai

Allen, reborn into an otome game, has finally recovered his memories. Now he knows that he has only a few short years to prevent the heroine from destroying his home and family…but how?! Not only is he an NPC, he’s the least relevant NPC in existence, without even an actual name! However, all is not lost. Armed with his memories, he vows to make full use of his greatest cheat code—game knowledge—and change his destiny! Using his knowledge and skills gained from menial labor, he manages to become a C-rank adventurer and enter the fabled academy grounds. But will his efforts be enough to defeat the heroine and save the villainess, or is an NPC all he’ll ever be? (Source: Seven Seas Entertainment)
