Mahoutsukai to Deshi no Futekisetsu na Kankei

Hard working, level 1 magician Konoha is apprenticed to lazy Knight Protector Saionji Ikumaru. They both work to keep the etherworld sealed away from their own but sometimes the seal doesn't work. Dragons, demons and now Ishtar, the goddess of Venus. Will Ishtar help Konoha win her master's affections? Or will she take him for herself?

The series contains following tropes

 * Action Girl - Konoha is one of the politest examples.
 * Affably Evil - Kazune
 * Anti-Magic - Saionji can use to absorb all magic in the area.
 * Back From the Dead
 * Bare-Fisted Monk - Albeit Konoha always claims that her Strengthening Magic is not that special, it seems to be enough to defeat a dragon!
 * Beleaguered Assistant - Poor Rui.
 * Big Brother Mentor - Saionji was this for his little sister.
 * Brilliant but Lazy - Saionji now, but he use to be . On the other hand Kazune will prefer to listen to music all day than work.
 * Catch Phrase - Momoka´s "That´s the duty of a high ranking magican."
 * Chaste Hero - Poor Konoha, her crush Saionji has nearly no sex drive.
 * Child Prodigy -
 * Crouching Moron, Hidden Badass - Saionji looks like a slacker, but he´s in fact very capable!
 * Cute Bruiser - Konoha may be really a nice girl, but this doesn´t stop from beating up demons.
 * Even the Girls Want Her - After she was rescued by her, Arumi became very devoted to Konoha.
 * Fan Disservice - Saionji´s Shirtless Scenes are not pretty.
 * Innocent Fanservice Girl - Minami. She seems to actually like it.
 * Jerkass: Arumi. She bargued into the house, assaulted (hitted), offended (perveted, pentaneko) and accused every single resident with the delicacy of a ramping train. She is quite probably one of the most offensive and annoying characters in the manga.
 * Katanas Are Just Better and Everything's Better with Samurai - Suwano Haruka
 * Meganneko - Rui
 * Muggles - Normal humans... and Arumi
 * Naked Apron - Well, you can't say that Konoha isn't trying.
 * Nightmare Fuel - Saionji´s
 * Noble Demon
 * Our Demons Are Different - They are nothing but an intellect surrounded by magic power. Therefore Saionjis Anti-Magic skill is deadly for them!
 * Rapunzel Hair with Girlish Pigtails - Again, Ishtar.
 * Really 4000 Years old - Ishtar.
 * Too Dumb to Live: Arumi. She decided to intrude and spy a high level Magic council because she deserved to had her curiosity satisfied, not to mention her reaction to demons, danger and magic in general. If she was in any other work she would be dead (or throrougly beated) by the first five minutes.
 * Token Mini-Moe - Ishtar.
 * Weirdness Censor - Averted when Arumi immediately reports Suwano Haruka to the police after seeing her standing atop a telephone pole.
 * Yamato Nadeshiko - Konoha.
