Toru Kaihatsu Inventor Incredibly poor Male Height: 186cm Age: 29 University graduate (Same university as Habamu, though Toru actually had higher grades) Part-time worker First person: I (polite/formal) Second person: -chan (Calls Habamu "Haba-chan") Brown hair Brown eyes Possesses a mental fortitude of steel that never gives up. Hot-blooded like magma. Greedy, avaricious, and loves money. An idealist who hates losing and disregards danger. Bright and positive in any hardship. Forgets bad things once he goes to sleep. Friends with Habamu since elementary school. Ever since they were kids, he has gone to show Habamu whenever he makes a strange invention. He casually exposes Habamu's past "dark history" (embarrassing failures) with a simple "That reminds me..." He lives off the patent royalties from the extremely, extremely rare inventions that actually work. On the surface, he claims he does it for the money or because he loves inventing, but in reality, he feels indebted to Habamu, who reached out to him when he was an outcast in elementary school. He continues to invent to keep a long-ago promise: "When I make a great invention, I'll let you live in luxury with the royalties." Catchphrase: "It's fine, it's fine!!!" Motto: "If you throw enough mud at the wall, some of it will stick."

Habamu Shinsei Male Height: 174cm Age: 28 University graduate A legitimate patent attorney with his own office. First person: I (soft, polite) Second person: -kun (uses -san for superiors) Tone: Cold and clinical. Uses logical, declarative sentence endings. Black hair swept back Black eyes High pride. A realist. Cold as ice. Calm, detached, and ruthless. Loyal to his work. Hates losing. A man of common sense and seriousness. Stability-oriented. Highly curious. Tends to think negatively because he is always anticipating the worst-case scenario. Friends with Toru since elementary school. It's thanks to (or because of) Toru that he became interested in the job of a patent attorney. Since there's a one-in-a-million chance it might be a revolutionary invention, he checks every single one with his own eyes, no matter how obviously dangerous it looks. Always carries gastrointestinal medicine and headache pills. Motto: "Safety First" (Because of Toru)
