Terashima Kengo

The protagonist of this work. A student attending the same school as Kana. He possesses academic ability, athletic ability, and a deftness that allows him to handle anything competently, yet he lacks any outstanding talent.

One could say he's an all-around type, but Kengo himself feels he's just an average person who does everything moderately well.

He met Kana when he spoke to her while she was lost in the old school building during enrollment, and they became acquainted, often talking since then. During spring break after advancing to their third year, Kana confessed her feelings to him.

At the time, Kengo was single with no particular crush, so he accepted her confession and they began dating.

Their relationship progressed with Kengo taking the lead—first kiss, caresses, then sex. When he visited Kana's house, he encountered Sayuri and became captivated by her mature feminine charm, something Kana lacked.

It was crazy to be aroused by his girlfriend's mother as a sexual object. He understood this rationally, yet as his relationship with Kana continued, he remained drawn to Sayuri's overwhelming feminine charm.

Unable to bear it any longer one summer day, he confessed his feelings to Sayuri and forcefully took her.

He joined the soccer club immediately after entering school. He handled any position—defender, midfielder, forward—with ease, making him a promising new recruit. However, his relationship with a female manager became an issue, leading to his withdrawal from the club.

Since then, he hasn't joined any club and enjoys being part of the “go-home club” (a term for students who go straight home after school). With above-average grades, athletic ability, and decent looks, he was popular with girls.

Even after breaking up with the soccer club manager, he quickly found another girlfriend. He accepted every confession without deep thought, starting relationships, but since he didn't genuinely like them, he gradually treated them carelessly. None of his relationships lasted long and all ended in failure.

Because he changed partners frequently, some boys and girls whispered behind his back that he was a womanizer. However, he never cheated on a girlfriend with another girl while they were dating.

That said, he has an extremely strong sex drive. With every girlfriend he's had so far, he demanded sex almost immediately after starting the relationship and had sex constantly.

He himself isn't aware of it, but he possesses a penis so impressive that girls swoon over it.
