Second season of Showtime! Uta no Oneesan datte Shitai.

Kairi stepped out of the air-conditioned bus and had to squint his eyes from the blinding sunlight and summer heat. When he slowly opened his eyes, he saw the sparkling azure ocean in front of him, with the clouds adding pockets of white to the sea of blue, and he smelled the faint scent of the ocean brought in by the gentle breeze. He moved here from the city to live with his grandfather after his parents went abroad for work. The kind townspeople welcomed him to their town, including two girls Haruka and Yuzuki.

Would you like to spend a wonderful summer break together with them in this town?

In the past as children, Kaname and Elcia were caught in a building in which a fire had broken out. Elcia got stuck under some rubble, and Kaname didn’t plan on giving up on her, even though it seemed hopeless. Just as Kaname was about to run out of strength, a modern-day knight saved them. After the incident, they both decided and promised each other to become knights and to protect and uphold justice and righteousness more than any other. Years later, they fulfill their promise to each other and work side-by-side to protect and uphold justice, while love starts growing in their hearts.

Keiichi Oyamada has a mysterious power that always makes him seem like a lucky pervert, as one way or another, he ends up having sexual intercourse with any female he meets. Due to this, he has never had a stable job as he continually gets fired from any place unfortunate enough to employ him.

One job opportunity arises when his best friend calls him to work at a manga cafe, which Keiichi reluctantly accepts. However, as soon as he starts his new job, he meets Rei Suzukawa, a fellow employee, and Kururu Hiiragi, his childhood friend. Both of them are very beautiful, and Keiichi fears that even they might not be spared by his lucky perverted powers.
