Story setting

Paradise Island Technology
Paradise Island Tech (abbr. P.I. Tech) is a cutting edge laboratory in the research of newly discovered microorganisms and has branches and facilities in many countries. Paradise Island Tech is the discoverer of Tamas, and hires the player as a lab technician to help research on the habits of Tamas. Luna is also an employee of P.I. Tech.

P.I. Tech is not short of outstanding researchers or research fund. It recruits the player, a layman, and asks the player to earn fund themself because the player's reaction is also a part of the experiment.

S.I.N.A. project
The research project initiated by P.I. Tech on the newly discovered species Tama. S.I.N.A. is the initials for "Social Intellectual Nano Anthropoid", the very first term given for Tamas.

Luna
Luna serves as the “showgirl” of Tama Tama Paradise. She is the representative and lab assistant assigned to the player by their employer P.I. Tech, and her role is to guide the player through new employee orientation. She always wears a friendly smile, not too sincere but also hard to be affirmed as fake. She seems to be aware of the hidden cruelty of the S.I.N.A project, and yet shows an unconcerned and innocent attitude towards the facts that she knows. She is much closer to the P.I. Tech management than the player.

Tamas
Discovered by P.I. Tech in a hydrothermal vent in the East Pacific Ocean a month ago, Tamas are the first-tier focus of P.I. Tech. Since the research on Tamas is in a very early state, previous Tama researchers have not yet had any clear facts about Tamas.

Tamas are unprecedented in biology. Researchers have not identified Tama's position on the modern biological taxonomy system. The most credible hypothesis is that Tamas are a type of jellyfish or enormous unicellular algae. A Tama is a slightly oblate sphere of about 1cm diameter. Its body consists of an unknown homogeneous mass that emits dim light.

There are two subtypes differentiated by colour: the Subtype R red Tama, the Subtype B blue Tama. Tamas's direct source of food is the lighting star-shaped substance named "Light Manna". It is not clear yet how Tamas produce Light Manna but they can only take in Light Manna produced by other Tamas of the same subtype.

Tamas has strong sociality: they tend to stay close to others of the same subtype and release "Dark Manna" to attack those of different subtype. Immature Tamas has a light orange colour: they can take in Light Manna from both subtypes and will not be the target of Dark Manna. After eating a certain amount of Light Manna from a subtype, immature Tama transfer to the subtype.
