That is Basic Starting Summary of Kuusen Madoushi Kouhosei no Kyoukan. Humanity has been driven from Earth's surface and is now leaving floating cities where Science and Magic combine. Normal weapons did not harm those bugs after they first attacked, so new kind of Warriors, "Wizards" where born. One of the main condition to remember any person who has been killed by bugs and there are 2 types of Wizards. Basic Warriors...and Best of the Best; Aerial Combat Wizards, so called treasure's of the humanity.
Main character Kanata Age live's in Academy City "Mistgun" as member of the City's Defense Force, "Guardians". For yet unknown reason he is know as traitor, but he is not letting it to make him feeling down. Story start's when he is named as instructor to the group of F-class fighters of the Aerial Combat Wizards whose personalities caused them falling their test and simulations so far.
Kuusen Madoushi Kouhosei no Kyoukan start's as basic adventure, harem actions story with used basic plot, Male MC meeting potential harem members before story start for real, he winning their hearts and in future war between Bugs and Wizards and maybe drama and plots-in-the-darkness between the battle's
By the first chapters story is OK, art is somewhat compensating the story. But it is basic harem adventure story, that can be read if you want so.
