Mahiru Shiina (椎名真昼, Shiina Mahiru) is the female lead of The Angel Next Door Spoils Me Rotten. She is the next-door neighbor of Amane Fujimiya and attends the same high school.

Personality
Due to her parents basically abandoning her, both physically and emotionally, Mahiru was raised by a housemaker, Koyuki-san. Like a lone flower at an unattainable place[1], she is very withdrawn. She hides her thoughts and feelings under a figurative mask, always seeming angelic, if distant.
