My Witch Trial Resets Every Loop

Chosen by the great witch Yukishiro Yuki, Nagumo Minato transmigrates into the world of Witch Trial, searching for fragments of the witch through repeated tender killings and returns from death. And all of it is for the ultimate salvation of the magical girls standing before him! Hasumi Leia: "Sometimes my ability doesn't seem to work on you, but I still hope you'll keep your eyes on me a little longer, Minato!" Kinosaki Noah: "Noah... likes drawing with Minato!" Tachibana Yuki: "Minato-kun, let's arm wrestle! If you lose, you'll have to be my boyfriend!" Hoshou Marg: "Alalala, what an interesting man..." Sakuraba Emma: "Minato-kun, I believe in you. We'll find a way off this island!" Nikaido Hiro: "You say you want to save everyone, but really you just want to date every girl... Damn it, I have a time-reversal skill, so I won't fall for it!" Yukishiro Yuki: "Then use your conviction to save everyone and show me why the human race deserves to continue existing!" (Every playthrough has different cases and settings. The first playthrough has fewer everyday scenes, while the second and later playthroughs have plenty of romantic moments.)
