■ Story

During summer vacation, an intensive training camp is held for middle school tennis players from across the country. To train their minds and spirits on an uninhabited island, the ship sets sail with the players on board—but they are caught in a storm, and only the players end up washed ashore on the island.

The heroine, whose father is the ship’s captain, and her friend are caught up in the incident as well. With no adults around, they somehow have to survive for the next few days.

The princes seem to be setting up camps in two locations: by the sea and in the mountains. Choose one of the camps, and your life with them begins.

■ Characters

◆ Mountain Route Group

A group based at the mountainside camp, led by Tezuka of Seigaku. While worrying about your father, who went missing during the shipwreck, you continue exploring the island together with dependable players.

What awaits you in the mountain area…?

The Crop Circle (Stream)

While exploring the island, Kikumaru claims to have discovered a crop circle.

With Kamio’s report of a UFO sighting added to the mix, Kikumaru, Kamio, and Mukahi become excited by the idea of an alien encounter—only for Inui to dismiss it outright, stating that the probability is “almost zero.”

Determined to prove Inui wrong, the three decide to search for evidence of a UFO and return to investigate the area upstream where the crop circle was found.

The Mystery Cave and Abandoned Village

Nioh discovers a cave hidden behind a waterfall. Around the abandoned village nearby, Fuji and Yanagi sense a mysterious gaze watching them.

Tezuka dismisses all reports as nothing more than imagination and orders the exploration to be halted.

Feeling something is clearly amiss, Fuji, Tachibana, Oshitari, Sanada, Yanagi, and Nioh defy the order and head toward the abandoned village to investigate further.

The Old Mansion

Kirihara discovers a suspicious old mansion at the edge of a forest that covers much of the mountain area.

After hearing that there are signs of human presence, Ryoma, Kaidoh, Ibu, Hiyoshi, Yagyu, and others take an interest.

However, Tezuka forbids any further investigation, stating that there is no need to examine dangerous places.

Convinced that something is hidden within the mansion, six of them decide to explore it secretly, without Tezuka’s knowledge.

The Ruined Abandoned Hospital

Kenya discovers an abandoned hospital far from camp and proposes investigating the clearly suspicious facility.

Driven by curiosity, Kintaroh and Chitose eagerly agree, while Shiraishi also supports the idea, reasoning that there are no other leads.

Tezuka rejects the proposal, warning that the building contains many dangerous pieces of equipment.

Though the explanation sounds reasonable, the Shitenhoji group cannot shake their sense of unease and secretly heads out to explore the hospital.

Doubts About the Leader

Oishi reports that he has found Sumire Ryuzaki on the island, who had gone missing after the shipwreck.

However, Tezuka not only postpones the suggestion to search for her immediately, but also orders Oishi to remain confined to the lodge for “losing his composure.”

As doubts toward Tezuka grow within the mountain group due to this harsh decision, Oishi, Kawamura, Inui, and Momoshiro appear convinced that Tezuka is acting with a hidden intention.

◆ Sea Route Group

A group based at the seaside camp, led by Atobe of Hyotei.

Using your natural cheerfulness and courage, you build trust with the players while continuing to explore the island

The Crop Circle (Field)

While exploring the island, Minami reports finding a strange pattern resembling a crop circle in an open field.

Jackal’s testimony that he witnessed a UFO-like object fuels the speculation, leading Kentaroh to propose a theory that there may be a UFO base on the island.

While most dismiss it as nonsense, they recruit Yuta—the only one who shows interest—and the four perform a ritual known as “Contactee” in an attempt to summon a UFO.

The Treasure Map

Akazawa discovers a mysterious cave inside a cliff that collapsed during an earthquake.

The location matches a spot marked with a red symbol on an old map found by Shishido.

Excited by the possibility, Kurobane and Marui speculate that it may be a treasure map.

Under Mizuki’s direction, the group examines the map, revealing a hidden message through a heat-based trick and uncovering a map of the cave’s interior.

The Dinosaur’s Shadow

In a fog-covered forest, Sengoku encounters a massive shadow resembling a dinosaur.

Yukimura also claims to have found dinosaur footprints similar to those he has seen in an encyclopedia.

Although Atobe dismisses the idea as ridiculous, the fact that there are two witnesses leaves Sengoku and Yukimura uneasy.

You head toward a nearby lake where the footprints were found along with the eager Akutagawa, Saeki, and Amane who call it a major discovery—and without Atobe’s permission.

Conflict Among the Members

Refusing to interact with the others, Kite, Hirakoba, and Kai isolate themselves at a separate lodge and act independently.

They conclude that the shipwreck was a conspiracy orchestrated by Atobe—and by extension, Hyotei—and continue to treat him as an enemy.

During this time, Atobe is bitten by a venomous snake and falls into critical condition, leading Yukimura to assume the role of acting leader.

Taking advantage of the situation, three members from Higa openly voice their dissatisfaction with Atobe and clash with Otori, who admires him.

At the same time, tensions also rise between Kite and Akutsu.
