[R +13] [Mild Nudity] Maburaho

Our main character is the seventeen-year-old high school student, Kazuki Shikimori. He attends the elite school for training people in the art of using magic, Aoi Academy, but as for his grades, it would be faster to count his rank starting at the bottom. On top of that, he can only use magic eight times in his whole life! Because he'll turn into dust if he uses up his magic, he spends his days depressed, unable to even use magic.
One day, a girl named Yuuna Miyama shows up in front of him. "From now on, we're husband and wife!" While he is still shocked, Kuriko Kazetsubaki and Rin Kamishiro appear before him. They have but one goal. To get the genes from Kazuki that hold the world's most powerful magic...
What destiny awaits the failure of a wizard, Kazuki Shikimori, who is suddenly being targeted by three beautiful girls!?

Characters:
Shikimori, Kazuki [Main] - The male lead character, Kazuki, is a second year student from an elite magic school, Aoi Academy, with serious social problems, and because he has a low spell count of only eight spells, most of the other students, especially the girls, would not notice him until his magical heritage is revealed.

Miyama, Yuna [Main] - Yuna, the typical harem anime "housewife," transfers to Aoi Academy to become Kazuki's wife and even first introduced herself as "Yuna Shikimori" to the rest of Kazuki's class.

Rin has a reserved and dignified personality and always dresses in a samurai-style kimono that is suitable to her warrior nature. Rin is ordered by the head family to secure Kazuki's genes in order to ensure the Kamishiro family's dominance, which according to Kuriko, has been weakening because of the number of branch families

Yamase, Chihaya - Chihaya, or Yamase as Kazuki calls her, is Kazuki's childhood friend and is in the same year as Kazuki at Aoi Academy.
