List of In Which A Shut-In Boy is Reincarnated as a Goblin characters

The following is a list of characters who appear in In Which A Shut-In Boy is Reincarnated as a Goblin.

Main Characters
Rioma (リオーマ, Rioma)
 * Voiced by: Yusuke Kobayashi (Japanese), Jason Liebrecht (English)
 * Rioma was once a shut-in teenager living in Japan who longe to be like the heroes who he played as and followed in RPGs and fantasy series. While attempting to defend a girl from a drunken man, Rioma was pushed and cracked his head on the concrete road, killing him. He was then reborn into the fantasy world of his dreams, only to discover that he was a goblin and not the hero he wished he was. Initially disheartened by this realization, Rioma would stumble into success when he helped defend his goblin village against invading adventurers, killing one of them in the process and absorbing their Mana Glyph. The glyph granted Rioma the ability to learn spells and absorb mana, which was unheard of for monsterkind. Using his new ability, Rioma sets out to become the defender of monsters, making numerous allies and enemies along the way while steadily growing his talents an spell list. Early in the series, Rioma ends up reaching a high enough level to evolve, transforming into a hobgoblin and becoming taller. It's also revealed he is the wielder of the Pride ability, which is claimed to be a particularly powerful Hero Ability that corrupts the user's mind when used too often. This combined with Rioma's self-proclaimed status as the Defender of Monsters causes him to be viewed as either a great hero or a threat to other's way of life.

Iris (イリス, Irisu)
 * Voiced by: Rie Murakawa (Japanese), Jad Saxton (English)
 * Rioma's most frequent traveling companion and best friend, Iris is a demihuman with cat ears and a tail. She is of the Mage class and is self-proclaimed as a horrible mage, though in reality she is actually so full of mana that her body doesn't know what to do with it, resulting in her often overcasting spells. She is characterized as being timid around strangers but with a thirst for adventure and a love for adrenaline. It is eventually revealed her shy and submissive nature was spurred on by childhood trauma, as a band of slavers murdered most of her village and took the survivors to be sold off. She was the only one who escaped and was eventually found and taken in by the Archmage Desmond, who taught her the way of magic.

Glacia (グレーシア, Gureshia)
 * Voiced by: Chiwa Saito (Japanese), Kayli Mills (English)
 * The Ice Dragon of Mount Gelid who becomes Rioma's Familiar, able to be summoned by him at any time. She also possesses a human form that she can shift to at will. She is incredibly powerful, with other monsters fearing her, and is very full of herself, to the point of referring to herself in the third person as "the Great Glacia". The only person she seems to view as superior or on-par with herself is Rioma, who she refers to as her master due to her status as his Familiar. She swore herself to Rioma after Rioma nearly died saving her life, at which point she sacrificed some of her own lifespan to save him. Having grown attached and maybe a little clingy to Rioma, she demanded to be his Familiar, not wanting to leave his side in case he ever puts himself in harm's way again. It is heavily implied she is in love with Rioma, though he seems unable to realize this due to only being able to see her as a kind of sibling figure. Later in the series, she is crowned a Dragon Lord, adding to her already immense strength and giving her standing in the political world of dragons.

Legendary Heroes
Katsu Uchida (カツ ウチダ, Katsu Uchida) / The Black Paladin (黒のパラディン, Kuro no Paradin)
 * Voiced by: Yoshitsugu Matsuoka (Japanese), Bryce Papenbrook (English)
 * Referred to as the Black Paladin for most of the series, Katsu is a Reincarnated One, like Rioma and a handful of other characters are. He is of the Chosen Hero class and is claimed to be the highest level hero in the world, with all of his Talents being Rank S. While a hero to his people, he is seen as one of the most horrific villains that monsterkind has ever seen, as he frequently conducts raids and XP grinds which often involve mass genocide. He is a narcissist who is the self-proclaimed "main character" of the world and is also demonstrated as being entitled to women and petty, responding to percieved slights with anger and sometimes violence. He is the only other known wielder of the Pride Hero Ability and serves as the primary antagonist for most of the series.

Saintess of Light (光の聖女, Hikari no Seijo)
 * will be added soon

Deities & Spirits
Spirit of the Forest (森の精霊, Mori no Seirei)
 * Voiced by: Go Inoue (Japanese), Patrick Seitz (English)
 * The primary guardian spirit of the Kuroki Woods. Throughout a majority of the series, he takes the form of a large tree at the center of the forest, with his spiritual essence residing in a green orb nestled inside. He is also Rioma's mentor, having taught him the secrets of magic and swordsmanship, as well as being the one who named him. He is also in charge of a small group of minor spirits called Nature Sprites.

Solus (ソルス, Sorusu)
 * will be added soon
 * The benefactor of most Chosen Heroes and the god worshipped by the Rombad Holy Empire, Solus is the goddess of light and the secondary antagonist of the series. She is a being described as one of the primary creators of the known universe, with her creating the Heavens and the sky. She primarily communicates via her "puppet", which is a vastly weaker version of herself, and she is responsible for seperation of the Creatures of Light (humans, elves, etc) and the Creatures of Night (monsters), as she believes that society functions properly only when one class is lording over another.

Demon Lords
Lucifer (ルシファー, Rushifa)
 * will be added soon

Asmodeus (アスモデウス, Asumodeusu)
 * will be added soon
 * The Demon Lord of Lust and ruler of the Island of Desire. He is notable for being the only Demon Lord to have land in the Mortal World, though all of his people are put under a spell that forces them to give into their base desires, no matter what they are. During a rise of Feral Monsters, Asmodeus becomes the primary suspect and Rioma temporarily joins his army in order to spy on him, though it eventually ends in Rioma revealing his true motives and absorbing Asmodeus's life essence. When he was active, Asmodeus was presented as being gigantic, around 15 feet tall, intelligent, egocentric, and with a scatter brained mind that caused him to leap from one interest to another.

Medea (メーデイア, Medeia)
 * will be added soon
 * The daughter of Asmodeus who takes over as the Demon Lord of Lust following her father's death. She is technically considered Rioma's wife, as during the time he worked under Asmodeus he concocted a lie that he was in love with her and eventually won her hand in marriage. Though she does seem to be in love with Rioma, she frequently flirts with or tries to seduce other men (and sometimes women as, despite being married, she has admitted to finding Iris cute), which she claims is due to her nature as a Desire Demon. Rioma doesn't seem to mind, viewing their marriage as a "political one". She is frequently used for comic relief, her strange perversions being poked fun at on several occasions.
