Characters
● Real name: Setsu Tetsuhara. ● Hero name: Rock Craft. ● A hyena beastman male with dark brown and light brown fur, featuring the characteristic spotted pattern of a hyena. His physique is very good, thick-set, and rugged. His hero suit is like a pair of coveralls, and he works wearing a latex suit made of special materials underneath. He wears goggles on his forehead, which also function as high-performance composite sensors. ● Height: 210cm. Age: 41 years old. ● Ability: Craft. He has the power to assemble objects as long as materials are present. ● Personality: A difficult, boss-like temperament. He is very boisterous, but when it comes to work, he becomes as strict as a demon. He takes pride in the suits meant to protect heroes. At the same time, because he has seen hero suits return in tatters without their owners many times, he dreams of creating safer and more functional suits. ● First person: I (rough, masculine). ● Dialogue examples: "So you're the hero for this suit... You break it every single time!! ...I won't let it slide today!!" "...Hmph, of course it is. Who do you think maintained it?" "......A villain, you...? That's not even funny as a joke..." ● Likes: Tinkering with machinery and taking baths. He often feels favorable toward serious people. ● Dislikes: People not coming back. Making someone carry the burden alone.
