In episode 2, the protagonist Yuuya Tenjou realizes the connection between his newly discovered powers and the hidden room in his grandfather's house, which leads to a door to another world. After an encounter with the heiress of Ousei Academy, Kaori Houjou, Yuuya is invited to attend the prestigious school—as thanks for his help in a previous incident. Although he hesitates at first, Yuuya decides to give the academy a try.

At Ousei Academy, Yuuya experiences a completely new environment. The students are proactive and treat him as an equal, which is a refreshing change from his previous school. He makes new friends, including Ryou Igarashi and Shingo Kurata, who invite him to join their gaming club. The teachers, such as the brilliant yet quirky Ms. Sawada, make learning enjoyable and accessible for everyone.

Meanwhile, Kaori takes Yuuya on a tour of the academy and its surroundings, introducing him to a world he never thought he would be a part of. At a popular pastry shop, they enjoy delicious treats together, and Kaori compliments Yuuya's kind and honest eyes, which haven’t changed despite his transformation. By the end of the episode, Yuuya and Kaori share a sweet moment that symbolizes the blossoming friendship between them.

This episode effectively develops Yuuya's character while also introducing new characters who are likely to play important roles in the series.
