Heavy Mecha Blues summary:
Eiji, a high schooler an in charge of the whole housework, gets a cute tsundere "maid" (She ist not exactly wearing a maid uniform) robot from his father on the occasion of his birthday. From Baka-Updates: For most people, having one’s own mecha sounds like a dream come true. So when Eiji’s father builds him his own girl mecha to help around the house, he thinks life is about to take a turn down easy street. Unfortunately for Eiji, his eccentric father isn’t about to make it that easy, and his new mecha girl seems to have a mind of her own – one that doesn’t necessarily take to doing what she’s told. Will Akira-chan prove to help Eiji’s life, make it more complicated, or a little bit of both?
