About: Daisuke Otobi - a name infamous throughout the scientific community as a half-crazed inventor of sex toys. Daisuke's eccentric nature has earned him a reputation for being unapproachable but he truly has the Haremverse's best interests in mind. He is always on the lookout for willing participants (who he likes to refer as "his pets") to test his inventions out on. Cries of pleasure are often heard from outside his lab.
Daisuke's hair is grey rather than black and his stubbles are more pronounced, he wears the same clothing as Okabe but with darker colors, with the exception of his lab coat. Both are very eccentric individuals who always acts melodramatic, they also like to invent gadgets though Daisuke's inventions are of naughty variants.
