Senko Amaguri  

, 甘栗 千子

The main character in the story is a female high school student named Senko who has an attractive appearance and large breasts. Despite this, she's known for being quite perverted and making sex jokes. She possesses two unique skills - the ability to sense erections and her Dual Chopsticks Attack that targets any erected dicks within range. As a result of her quirks, Senko doesn't have many friends other than Hoshi and Nao from the Manga Research Club she belongs to. Senko's family runs a Handyman Service, which she helps out with. She enjoys teasing Takamura, one of the live-in workers at her family business, due to his phimosis dick and his ability to get erect on multiple levels. However, as time goes by, Senko finds herself genuinely attracted to Takamura because of his kind nature, and she eventually encourages him to confess his feelings to her, which he does happily.
