★STORY

The protagonist travels to the planet Anderes on a second-hand spaceship,

accompanied by a support AI named John, to study alien life.

They land on Yura Island, one of many islands scattered across the planet.

Anderes is a developing world similar to Earth,

with countless islands floating across its surface.

There, you will meet aliens such as the Yatoko, Dracs, and Theloema.

As you spend time talking with them, the tone of your conversations

and the distance between you will gradually change.

Depending on your choices, they may open their hearts to you,

or quietly begin to keep their distance.

★CHARACTERS

●Lifelaease (Life)

A young Dracs man who sells items to the protagonist.

He is not good at talking about himself and is hard to read, but shows a gentle smile as you grow closer.

●Climsona (Krim)

A young Dracs man. Bright and easygoing, he always says what he thinks.

He resents the expectations placed on him and was raised by Lifelaease.

●Moumeu

A Yatoko girl with an eye implant that causes her emotions to appear in her eyes.

She is friendly, but becomes oddly flustered the more the protagonist talks to her.

●Sertoto

A young Yatoko man who supports the protagonist’s work.

He manages the island and organizes events, making him a reliable presence.

●Mehama

A Theloema man. Wealthy, fond of alcohol, and unconcerned with being liked or disliked.

He may seem cold at first, but becomes surprisingly indulgent once you grow closer.

●Haizo

A young Theloema man. A shy, game-loving shut-in.

Conversation is awkward at first, but he will start reaching out to you as your relationship develops.

★SPECIES (Details)

Yatoko — Highly advanced merchants with large ears and tails.

Average lifespan: 45–55 years

Fox-like aliens whose technology is so advanced it is almost incomprehensible to most species.

They develop weapons and devices, traveling between planets to trade and make a living.

Because of their technology, few would dare to oppose them.

Dracs — Long-lived, ectothermic aliens with horns and long tails; strong fighters.

Average lifespan: 300–310 years

They have clear, jewel-like horns and long, scaled tails.

Their civilization is roughly comparable to (or slightly behind) humanity’s, yet they readily use tools and weapons from other species.

With sharp claws and fangs, many Dracs were once forced into combat slavery during an era of interstellar wars.

A Dracs may reveal a “heart name” only to someone they truly trust.

Theloema — Said to be immortal; sensitive to bright light and dependent on blood.

Average lifespan: said to be immortal

They have slightly pointed ears and severe light sensitivity.

They possess unusual abilities such as physical enhancement and teleportation, and must periodically consume human blood.

On their homeworld, humans were once treated as livestock, but this practice has largely faded as blood packs have become easy and inexpensive to obtain.

★Author’s Note

This game is still in development, and the content above may change.

In particular, the number of endings may increase, as I’m considering adding more bad endings.

The setting is inspired by colony simulation games, so it may include themes such as illegal drugs and morally questionable depictions.

Please play only if you can enjoy it as fiction.

English subtitles are planned. The current English text is machine-translated, so please let me know if you find any awkward or incorrect parts.
