About

Situation / Suddenly, during summer vacation, Kuroi has started saying nothing but "Won't you go to the sea?" for some reason.

What is Private Paranomaru High School? ↓ Simply put: "A high school where students with supernatural abilities gather."

Worldview / In a timeline where everyone naturally possesses various supernatural abilities, it's not about hot-blooded battles, but rather the peaceful, lazy daily lives of high schoolers living with their powers.

~ Flow of the Story ~

  1. The day before summer vacation, Kuroi starts saying nothing but "Let's go to the sea."

  2. When Tada finished his part-time job shift with Kuroi, Tada asked, "...Is there somewhere you want to go?"

  3. Kuroi replied, "Let's get on a boat," breaking the "Let's go to the sea" loop for the first time.

  4. Tada asked, "Which boat?"

  5. Kuroi said: 3528166513947899543528166…… and continued reciting numbers infinitely.

After a few days, everyone gathered. Tada took notes and held a meeting to discuss "Why did Kuroi become like this?" and "When did it start?" Eventually, Taira suggested "Enoshima?" and Misato agreed "It's Enoshima." They took the train, climbed slopes, ate street food occasionally, and took a boat to Enoshima. Minutes later, Yamikawa, Kuroi, and Tada got motion sickness.

  1. Kuroi looked at the sea and said, "Let's go to the sea bleeegh..." while vomiting.

  2. When Enoshima came into view, Kuroi suddenly stood up and said, "Let's go to the island!! To the island!!" with a broken laugh.

  3. However, something was strange. "Doesn't the boat driver... feel anything?"

  4. Then the conclusion was reached. Busujima understood. "This guy, he gets weird when he leaves the island," she said. It was true. If he didn't leave the island, he was his usual cheerful self.

  5. Then, a boy in an orange short-sleeved shirt with mixed red and brown hair appeared. His name was— "Shion"

Island Lore and Plan: The four shrines located at the North, South, East, and West of Para Island were originally meant for offering sacrifices to "Lord Arahabaki."

Execution of the Operation: In the middle of the summer festival, a plan is made to scatter "Grape-flavored Powder" at each shrine to weaken the seals upon the signal of fireworks, angering Lord Arahabaki and awakening the god.

Truth: It turns out the need for sacrifices was a lie; Arahabaki never sought sacrifices. The villagers had simply imprisoned the god so their festivals wouldn't be disturbed.

Let's work together to return Kuroi to normal.

In the past, regarding Hoshidate Villain High, he tried to distance himself to avoid involving others, leading to a fight with Kuroi. His Luminescence, which previously couldn't beat Kuroi's Black Hole, was strengthened by a physics teacher; he initially won but lost the very last match.

Good at kendama.

Once, the day before a cultural festival, he woke up as a girl. Straight green hair down to the chest. He told his sister he'd skip school, but she said their mom was worried about his grades, so he was forced into his sister's uniform and went in a skirt. No one realized it was Hikaru. He tried to say "I'm Hikaru—" but Mirai just asked "Oh, is your name Hikari-chan?" and Taira gave the nickname "Pikarin." Later Kuroi arrived and turned bright red seeing Hikari. It was love at first sight; he introduced himself with a trembling voice, only to fall into deep despair and heartbreak upon learning Hikari was Hikaru. Turns into a girl when splashed with cold water, boy with hot water. This condition has since been cured.
