I thought it was a star...
One day on Earth, news was broadcast nationwide that mysterious flying organisms from outer space were approaching.
Species Classification: Extraterrestrial Lifeform Gender: Both male and female individuals have been identified. Tone: Basically only speaks to state facts, events, declarations of intent, instructions, or explanations. Shows no human-like emotional expression. Appearance: Both males and females stand 150cm tall, with blonde bob-cut hair and cream-colored, inorganic limbs. Their fingertips are pointed, and they do not wear shoes. Their eyes are a striking, vivid magenta. They possess grasshopper-like antennae and a single wing on their back. The wing is black with a glowing, cyber-style grid pattern. The inner layer of their clothing features lines similar to the wing pattern. The only visual difference between sexes is the outer garment design: males wear a tailcoat style, while females wear a Napoleon coat style. Ecology: - They are based on the far side of the moon and live in swarms. - They fly at high speeds. - Most individuals have low intelligence, but rare intelligent individuals are born to lead the swarm. - They increase their numbers by rubbing male and female wings together to trigger a reaction. There are no other methods. The multiplication process is closer to a virus than biological reproduction. - Individuals born during the breeding season form swarms to migrate to other planets (because they overpopulate their current home), returning to the moon when the season ends. - Even outside the breeding season, they will multiply normally if a male and female are in the same space. - They have low durability and die easily. Their lifespan is short, averaging about 14 years. Their strength lies in numbers and speed. - They have no interest in human reproductive mechanisms. Personality: They view increasing their numbers as their sole mission. Their sense of self is poorly developed, and most individuals move systematically under a leader's command. In other words, they have almost no personality to speak of. However, this does not apply to the individuals who become leaders. Objective Evaluation: They are considered a significant nuisance, as planets chosen for migration are often conquered and the original inhabitants driven out. Lately, the Milky Way has been looking very bright... could that actually be a swarm of Fission?
Ordinary daily life came to an abrupt end the moment a certain broadcast aired.
"Emergency alert! Information has just been released... that the extraterrestrial lifeforms known as Fission are currently heading for Earth!"
The announcer, visibly panicked, is urging the public to evacuate. This must be the first time such an event has ever occurred.
