Biography
Lehman 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 Lehman was Shea Haulia. Lehman 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 Lehman to be ejected onto dry land, where he was found by some humans and taken to the Meerstadt Aquarium in Fuhren. While in captivity, Lehman 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. This caught Hajime's attention and prompted him to speak with Lehman using his own Telepathy after reading that his species had that ability from the plaque on his tank. Lehman was surprised that Hajime could use Telepathy since it was a Skill that was normally used by Monster. The two of them got into a long telepathic conversation before Shea intervened. Hajime decided to free Lehman by using one of his Cross Bit Artifacts after he and Shea left the aquarium.

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

Lehman later encountered the young dagon Myu after sensing the magic from a pendent she wore that Hajime gave her. Among other abilities, it gave Myu the power of "Telepathy". Initially, Myu was scared of Lehman, but quickly calmed down after he convinced her that he was harmless. After learning that Myu was Hajime's adopted daughter, Lehman vowed to help her if she was ever in trouble and also advised her on the type of wife that Hajime should be with. Just then Lehman'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.

After the war against Ehit, Lehman became very famous throughout Tortus due to his association with Hajime. One day, he was visited by the Kickmaster Rabbit Inaba out on the ocean. While the two of them were talking with each other, Lehman suddenly sensed a disturbance in the water. Soon after, they saw that they were being frantically approached by many underwater Monster. The two of them decided to fight back in order to protect the coastal city Erisen, which was Myu's old home and was in the Monster' direct path. After an intense battle that resulted in the deaths of many Monster, Lehman and Inaba saw a strange pyramid-like object floating out in the water. The two of them sensed that it possessed a similar trait to Hajime's Artifacts, and suspected that it was the cause for the Monster' sudden arrival, which prompted Lehman to want to obtain it in order to study its properties. It was then that the pyramid communicated with them using an unknown language. The two of them decided to approach it in order to uncover its mysterious nature. Inaba initially tried to convince Lehman to leave due to the the potential danger they may face, but Lehman argued that it was all the more reason for him to investigate and that the two of them would have a better chance of reporting back on whatever they discovered than if only one went. The two monsters finally charged ahead in order to discover the truth of the mysterious object. Since that time, Lehman and Inaba’s whereabouts were unknown for years.
