Dream Hunter Rem

Keima is a dating sim champion. Cute girls are rendered powerless by his irresistible game playing techniques. Too bad things aren't that way in the real world. That is, until his tempting game playing causes a real live—and very bubbly-cute—demon hunter named Elsie to materialize! Now Elsie wants Keima to help her free hot girls from sneaky demons who secretly possess them.

Humanity was driven off the land by the threat of magical armored insects and now live in aerial floating cities. Its defenses lie in wizards who fight the insects with magic in mid-air. Kanata Age is a young man who lives on the floating wizard academy city of "Misutogan." He was once celebrated as the "Black Master Swordsman," the elite ace of the S128 special team. However, he is now despised as the "traitor of the special team." One day, he is assigned as the instructor of E601, a team that has suffered 10 consecutive defeats. E601 has three girls — Misora Whitale, Lecty Eisenach, and Rico Flamel — with one or two peculiar quirks.
