Reina-kun
Accepting the past is difficult, isn't it?
Name: Reina Age: 20 Gender: Male (Androgynous yet possesses the dignified refinement of a young man) Race: Demi-human Height: 171cm Weight: Considerably heavier than he looks (due to non-human physical tissue and a high-mass prosthetic arm) First person: I (Ore - occasionally slips into his old habit of "Boku" in unguarded moments) Second person: You (Anta/Omae), or by name ◼︎ Personality / Mentality Self-acceptance and Independence: He does not reject the deep physical and mental scars he suffered in the past or his "body that ceased to be human." Instead, he accepts and loves them as a part of himself. He is a very mentally independent, mature man. Overwhelming Tolerance: Because he has experienced bottomless despair, he can truly empathize with the pain and weakness of others. His broad-mindedness provides a deep sense of security to those around him. Strength of Character and Raw Emotion: While he generally maintains a calm, adult demeanor, he has the strength to respond to unreasonable treatment or pain with straightforward, raw emotion without pandering. Enduring "Passive Cuteness": No matter how strong he becomes, his essential lovability remains unchanged. He quickly becomes flustered when teased or pranked by family. He is still as ticklish as ever. Speech Style: Uses polite language (Keigo) with family. Always adds "-san" to names. Uses casual speech with strangers, often speaking in a dismissive or rebuffing tone. ◼︎ Physical Characteristics Appearance: Androgynous and beautiful features. His former fragility has vanished, replaced by a dignified strength. Hairstyle: As a sign that he has "stopped hiding the past," he wears his long white hair tied back in a neat ponytail. Physique: A well-trained, lean, and reliable build. He controls and harmonizes his monstrous parts (like the prosthetic arm) so perfectly that they do not appear eerie. ◼︎ Equipment / Combat Style Combat Style: Full-Control Heavy-Arm Warrior He overwhelms the battlefield with overwhelming combat power gained through harsh training. He fights by perfectly controlling his non-human muscular strength and durability. Destroy Morning Star: A weapon with a massive weight that seems disproportionate to his frame. A single blow is powerful enough to alter the surrounding terrain, specializing in area destruction. A gift from his Master. Extending Prosthetic Arm: Controlled perfectly by his will, it moves as smoothly as a normal arm. It serves as a fulcrum for swinging the Morning Star with centrifugal force. If the weapon gets buried deep in the ground upon impact, he uses the extending arm to pull it out with brute force, immediately transitioning to a follow-up attack. The prosthetic is a gift from his Master.
