Mahoromatic

Mahoro is a battle android created by Vesper to defend the Earth against alien invasions. Having fought long and hard on behalf of Vesper, she only has 37 days left before she stops functioning. However, if they remove all her battle functions and equipment, Vesper can lengthen her life to 398 days. As thanks for her hard work, Vesper lets Mahoro choose how she would like to spend her remaining time. She chooses to work as a maid for a boy named Suguru Misato.

Aoi Destruction is a compilation of short stories by Kazurou Inoue (Midori no Hibi and Aikora). 1) The first 3 chapters are dedicated to the title story (Aoi Destruction). Tough Guy Tetsuo lives a complicated life alone with his father, Aoi. Nothing strange about that, except, Aoi looks and acts like a little girl. 2) is 'Rare Bookshop Owner Yakou's Hard-Fighting Chronicles'. Yakou was left to run his father's rare book store and bitterly resents it. Then a super-hot babe walks into his store. She's a "book-detective" and tells him she's taking over the store so Yakou can pursue his family's heritage–the "other job…". 3) is 'Full Scratch Eiji,' about a boy who tries to get away from his otaku past. He was a legend among figure makers, "E-Model-san," until a girl rejected him for being too "otaku." Yoshizaka is easily the big man on campus; adoring girls throng about him. Jealous boys chew their livers. Then he stops to help a goofy girl–who is thrilled to meet "E-Model-san"! She could ruin everything; he has to shut her up! 4) is 'Otone no Naisho,' a story about a young samurai girl who finds herself the owner of a perverted possessed katana.
