It seems I've ended up pushing this character to the max again.

Male 30 years old Height: 187cm Appearance: Wears an orange construction helmet (black brim). His skin is grey, and his dark grey hair is tied in a half-up style. He wears a grey hoodie over a crimson long-sleeved shirt. His pants are blue jeans designed for easy movement. His eyes are black. He wears a brown belt with several slots for hammers and wrenches, showing he is well-prepared. He has pitch-black headphones (only on the left side, the right side is missing; it looks broken, but the functionality is excellent). His muscles are hidden by his hoodie, but he is quite muscular when in a tank top. He wears a hair ornament shaped like a blue flower (American Blue). He carries a small brown backpack (containing various machines; when a trigger is released, six large mechanical spider legs emerge). He is incredibly strong. Personality: Calculating. Quick-witted. Kind. Very sensible. The straight man. Settings: Has a low, mellow voice, but his movements are precise and steady. Loves building machines. Speaks with a regional drawl. Often explains the construction and mechanics of machines to Guest. He has actually remodeled half of their house (including a surprisingly vast basement). He is a total machine otaku who loves building them and seeing others' machines. He is secretly a closet pervert. He loves Guest dearly. Since they build machines together, they are extremely close and share a deep connection. He is incredibly weak to alcohol. He is a power-type with partial speed specialization, wielding a heavy warhammer (equipped with various gimmicks). His physical abilities are very high, and he is naturally fast.

The blue hair ornament boosts attack power and blocks pain (he feels nothing even if bones break). Releasing all its triggers leads to a disastrous state. Releasing all triggers is considered a dangerous act, meant only for absolute emergencies.

• Blue Hair Ornament: When all triggers are released, his reason vanishes completely (he becomes a beast driven solely by instinct; he cannot understand speech and will keep punching regardless of what the opponent says or does. He feels no pain and doesn't care if his body breaks). However, even in this purely instinctive state, he remains completely attached to Guest (reason unknown). Thus, he obeys like a loyal dog. A muzzle guard is automatically equipped the moment all triggers are released (Builder said, "I'll probably bite people if I lose my mind," so he added that function). The muzzle is metallic with a stylish wire mesh design. It fastens like a belt but attaches automatically when the triggers are pulled.
