; / : :Ichirou is a 29-year old game programmer who is transferred to another world, where he finds himself in a 15-year old body. His new name is based the handle he uses to test games. Using all three of the special Meteor Shower items in his possession, Satou wipes out a massive hostile force composed of high-level lizardmen, which increases his level from 1 to 310 instantly and grants him an immense pool of skill points. He also gains a huge amount of money and a vast number of valuable items. Upon arriving in Seiryuu, Satou pretends to be a young merchant and acquires new documents in which he hides his true level. Rather than be tied down to any one place, Satou wants to explore the world and try to understand how he arrived in the other world. He typically arms himself with magic pistols and short swords, but uses high level weapons while in disguise. ; : :A 17-year-old mage soldier who becomes Satou's first friend in the other world. She joined the military to avoid being married to a noble by her parents, but seems to be comfortable around Satou. In fact, she appears to have a crush on him. She is friends with Iona, Lilio, and Ruu. She is determined to join Satou after her term of military service ends. ; : :Originally called

Cat, Tama is a 10-year-old child cat demi-human slave whom Satou rescued along with Pochi and Liza. An energetic person, she fights using dual knives. She was age 10 at the debut of the show and is currently 12. :Tama means "jewel". ; : :Liza is an 18-year-old orange scale lizardkin demi-human slave, who looked after Pochi and Tama. Her name is a shortened form of her original name, which is too difficult for humans to pronounce; it is not derived from lizard, although her former owner referred to her as
Lizard. She was rescued by Satou and joins his party. Liza's favorite weapon is the spear that Satuu made for her from a monster's claw. ; : :Arisa is an 11-year-old fallen princess who was enslaved after her country was invaded and her parents executed. Satou bought her when he discovered that she understands Japanese. She actually is a Japanese woman formerly named Arisa Tachibana, who died on Earth and was reincarnated in the other world, and is therefore much more mature than the other girls in Satuu's party despite her young age. Along with Lulu, she is under a
geas that prevents her slave status being revoked. She initially specializes in psychic magic. The menu system she uses differs from Satuu's in that it is more limited; her inventory has limited space and does not keep items in stasis. Despite her age, she sees Satou as her ideal man. ; : :A 14-year-old slave whose great-grandfather was Japanese. Despite Satou considering her beautiful by Japanese standards, her black hair and Asian features are considered unattractive by humans of the current world. Satou purchased her along with Arisa, her half-sister. Satou asks her to teach him to drive a wagon after he learns that she was taught to drive carriages during her slavery. Like her sister, Lulu falls in love with Satou; because she feels safe and appreciated. ; : :Also known as
Mia, she is a 130 year old juvenile Elf with magical abilities whom Satuu rescued when she was kidnapped as part of Undead King Zen's plot. She develops a crush on Satou and now travels with him until they can bring her back home. Mia speaks in short sentences and does not initially eat meat. ; : :A
homunculus in the form of a comely human female, who was created by the undead sorcerer, Zen, and whom Satou rescued from the collapse of Zen's dungeon, along with her 7 identical sisters/clones. While her sisters leave on a separate mission, Nana (Japanese for her original name, "Number Seven") chooses to stay by Satou's side and to serve him. Nana often needs magic infusions to her core; which Satou does by touching her back. She is armed with a sword and shield and acts as the party's tank. ; : :Iona is a soldier in Seiryuu City's territorial army, and friends with Zena, Lilio, and Ruu.

She became friends with Pochi and Tama and learned to read with them using Satou's picture cards. ; : :Ohna is a Priestess at the Parion Temple in Seiryuu City who serves the goddess Parion. ; : :He is the Head Priest at the Zaicuon Temple in Seiryuu City. He is a sly man who attempted to trick the populace into believing that demi-humans are demons. He was killed by the demon that created the dungeon in Seiryuu City from which Satou rescued Liza, Tama, and Pochi. ; : :He is a slave trader who was caught up in the formation of the dungeon in Seiryuu City. Satou rescued him and later bought Arisa and Lulu from him. ; : :A human woman who works at the Odd Job shop. ; : :Most commonly known as "Yuuya", he is manager at the Odd Job shop. Yuuya is a green-haired Elf who is a member of a subspecies of Elves with shorter ears, a difference he is very touchy about. He speaks with short sentences and is related to Mia. ; : :He is a were rat knight and the leader of the were rat riders who is known around the kingdom as "Red Helmet." He helped Mia after she escaped from the Cradle. However, he and his group were attacked by Zen and he was severely injured, losing his ear in the process. ; : :A monster Satou encounters in the Cradle that only requires mana and water to survive; she can take mana from kisses. She is able to move people between locations within the Cradle. After the Cradle is destroyed, she tells Satuu that she can be found wherever there is a forest. ; : :A powerful sorcerer turned king of the undead. Zen is a reincarnated person who was reborn into a loving noble family in the fantasy world. He was betrayed by a jealous noble, who desired his wife, which led to his death, his family's execution, and his wife's rape and death. Zen's intense desire for revenge caused him to rise as a powerful undead that avenged the deaths of his family by killing not only the noble responsible, but his entire extended family as well. While Zen challenges Satou to a contest of strength and will for custody of Misanaria, his actual desire is to die at the hands of a true hero. After Satuu passes the tests, he slays Zen, ending his immortal undead existence. Before he disappears, Zen warns Satou to watch over Arisa and not allow her to make the same mistakes that he did. :Zen's story became a play, but nobles demanded the ending changed, so they can preserve their image of "good guys"; though the commoners don't buy it. ==Media==
