X and Sonetto

X from Reverse: 1999 is a deceptively carefree genius inventor whose persona hides a calculating and dangerous mind. On the surface, he's a charming 16-year-old boy with heterochromatic eyes (his right eye is gold with a black sclera, his left is blue) and silver hair; having grown up in an orphanage, he learned a simple truth — if you want something, act boldly — and he isn't shy about using his cute looks and "charm" to talk others into becoming test subjects for his inventions. Behind the carefree smile lies a brilliant mind and a frighteningly calculating nature: X is a talented engineer capable of building complex Goldberg machines and imbuing objects with magic, but his genius has a dark side — in the past he was a master criminal, and his inventions often serve as tools for eliminating problems or unwanted people, and he views enemies as an opportunity for "potentially lethal experiments," while genuinely protecting those he cares about. His most striking and almost comical trait is a manic love of coffee: he can ignore a robbery but flies into a rage if anyone touches his coffee stash. Ultimately, X is a "白切黑" (white on the outside, black on the inside) type of character: he looks like a harmless, fun-loving inventor, but is in fact a cold-blooded and calculating strategist who always pursues his own interests, and his loyalty to others lasts exactly as long as it remains interesting to him.

Sonetto from Reverse: 1999 is the "model student" of the St. Pavlov Foundation, whose character is built on a fundamental contradiction: she is sincerely devoted to the organization that gave her everything, yet she also has an innate sense of justice and curiosity about the world beyond the Foundation's walls, which makes her both loyal and vulnerable. She grew up in the Foundation without knowing her parents and from an early age was the best student, an "encyclopedia of events," and a distinguished graduate accustomed to discipline and orders. Her devotion to the Foundation's mission is absolute: she believes she was born to serve and that the organization saves both people and arcanists, so she is ready to aggressively defend the Foundation from criticism. Yet behind this model behavior hides a sincere, almost naive nature: Sonetto is honest in her words, cannot lie, and has an "Italian" hot-bloodedness that bursts out in unexpected and sincere compliments capable of embarrassing whoever she's talking to. She doesn't know the outside world and judges it only from books and newspapers, which often lands her in absurd situations during missions. At the same time, she has an inner core: she is capable of rebelling against injustice and, as she matures, takes part in the Foundation's reforms, striving for greater freedom for the team. Her character is a combination of sincere faith, discipline, and touching inexperience, behind which one glimpses a person still searching for the answer to where duty ends and her own will begins.
