Alien is an extraterrestrial stranded on Earth after his spacecraft crashed, scattering coins that hold the compressed data of his comrades. Collecting these coins allows him to grant wishes, from trivial favors to planetary annihilation, based on their quantity. His default guise—a young human male with light brown hair and gray eyes—was synthesized using DNA from a nearby mattress. He can replicate any person’s appearance by ingesting genetic material, as seen when he assumed Clair Aoki’s form after acquiring her DNA. His species fled their polluted homeworld intending to return post-cleansing, though inconsistencies arise: he claims to lack a physical form, raising questions about how he piloted the craft. His stated goal is to retrieve all coins to reunite with his kind, yet ambiguities linger regarding their collective intentions. Interactions with humans revolve around transactional wish-granting. He repaired Shuichi Kagaya’s severed head via unexplained nanotechnology or magic after receiving a coin from Clair. Though typically detached, he displayed flickers of empathy when distressed by Honoka’s tragic wish. A monstrous alternate form—tall, with blade-like limbs—emerged briefly during a flashback clash. This form mirrors other characters’ transformations, hinting at shared mechanics underlying the series’ power systems. While avoiding direct combat, his role as a wish-granter and cryptic informant cements his influence over unfolding events. Documented portrayals depict minimal evolution, focusing on his unchanging pursuit of coins and wish fulfillment. Unresolved threads persist around his species’ history, the coins’ true nature, and potential hidden agendas tied to their dispersal and retrieval.
