Otto Suwen is a merchant appearing in Re:Zero. His remarkable misfortune always takes him to dangerous situations, from which he escapes thanks to his wit. Otto has gray hair that is mentioned to be as long as a gal game protagonist. He is said to be somewhat handsome if he has a serious expression. However, he is usually either retorting, shouting, or panicking, ruining his looks. He has a medium build, but has trained himself since he used to work as a merchant.
