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. He met Subaru in the Arc 3 episode 14 of the first anime season and since then he is a worthy ally in the main timeline.
