Hagure mono Saikyou Kuukan Mahou Tsukai wa Yome to Shizuka ni Slowlife Shitai
はぐれもの最強空間魔法使いは嫁と静かにスローライフしたい
Landros is a half-demon rejected by both humans and demons. He develops feelings for Char, the only person who has ever been kind to him, and vows to end the war threatening her. Using his unique spatial magic, he fights and defeats a powerful demon lord. Afterward, he settles into a quiet life, working to support his friends despite being mocked as a pervert or oddball. Reuniting with Char brings him joy, though unseen enemies plot to use her as bait to draw him out.
