Fish-san (リーマン) is a human-faced fish that Hajime met during his date with Shea at Meerstadt Aquarium.

Appearance
Riiman has an appearance of a fish, however his unusual appearance is his head which looks like that of an old man.

Personality
Riiman has a grumpy personality pretty much like that of an old man's, but he is actually very friendly and humble with Hajime and really appreciates Hajime's help when he saved him from the cage in the city. Another proof of his gratitude is when he stalls the monster near Merujine's Undersea Ruins that is attacking Hajime and his companions.

Background
Riiman was swimming in a river not too far from Brooke Town when it suddenly erupted due to Hajime and his companions getting flushed away from the Great Reisen Labyrinth by Miledi Reisen. The only one who spotted Riiman was Shea. Riiman looked at her and asked what she was looking at using telepathy. This shocked Shea and nearly caused her to drown after she inhaled some water.

The rupture in the lake caused Riiman to be ejected onto dry land, where he was found by some humans and taken to the Meerstadt Aquarium in Fuhren. While in captivity, Riiman would would once again meet up with Shea while she was on a date with Hajime. Shea was surprised to see the strange fish again and began to stare at it intensely. The caught Hajime's attention and prompted him to speak with Riiman using telepathy after reading the plaque on his tank that his species had that ability. Riiman was surprised that Hajime could use telepathy since it was a skill that was normally used by monsters. The two of them got into a long telepathic conversation before Shea intervened. Hajime decided to free Riiman by using one of his cross bits after he and Shea left the aquarium.

Riiman would meet up with Hajime again, along with the rest of his party and his entire party, outside of the Sunken Ruins of Melusine. They were fighting an ancient gelatinous aquatic monster called a devourer. Riiman used his telepathy to control a school of fish to aid Hajime. Though the devourer eliminated all of Riiman's fish, he was still able to give Hajime to time he needed to defeat it.

Riiman later encountered the young dagon Myu after sensing the magic from her pendent that Hajime gave her. Among other abilities, it gave Myu the power of telepathy. Initially, Myu was scared of Riiman, but calmed down after learning that Riiman was a friend of Hajime. After learning that Myu was Hajime's daughter, he vowed to help is she was ever in trouble and also advised her on the type of wife that Hajime should be with. Just then Riiman's wife appeared and dragged him down to the bottom of the ocean while complaining to him about not spending enough time with her or his children.
