Invaders of the Rokujouma!? (六畳間の侵略者!?, Rokujōma no Shinryakusha!?, lit. Invaders of the Six-Tatami Mat Room!?) is a Japanese light novel series written by Takehaya and illustrated by Poco. HJ Bunko has published seventeen volumes since 2009 under their HJ Bunko imprint, as well as two side story volumes. A manga adaptation with art by Tomosane Ariike is serialized in Hobby Japan's online seinen manga magazine Comic Dangan. A 12-episode anime television series adaptation by Silver Link aired between July 11 and September 26, 2014.


Kōtarō Satomi decided to live on his own when he began high school, and chose Room 106 of Corona House because it was cheap. Unfortunately, Kōtarō soon discovers that numerous otherworldly and supernatural girls also want his room for various reasons of their own, and aren't about to back down. As a result, Kōtarō and the girls find themselves forced to live together as they try to settle just who ends up with the room.


Main characters[edit]

Kōtarō Satomi (里見 孝太郎, Satomi Kōtarō)[3]
Voiced by: Yuichi Nakamura[4]
A high school boy who moves to room 106 and intends to keep it at all costs due to its unexpectedly cheap 5,000 yen per month rent. After an accident in the archaeology site he works at, he gains the ability to see ghosts and wield ancient artifacts. He usually is seen wearing the replica of the Blue Knight’s armor Theia has when fighting, along with using his two swords, Saguratin and later (after Volume 7) Signaltin. While at first not that experienced in sword fighting, he gains a much higher level of skill after he returned from Ancient Forthorthe in the past with Clan (Clariossa Daora Forthorthe) due to all the fighting he did there (explained in Volume 7.5 and 8.5)
Sanae Higashihongan (東本願 早苗, Higashihongan Sanae)[5]
Voiced by: Eri Suzuki[4]
A female ghost who haunts room 106. She wants to expel Kōtarō and claim the room as her own. She is able to manipulate solid items and launch them to attack, but her attack is neutralized when near sacred objects. Later, it is revealed that she is actually a soul who has left her body, and the room 106 residents work together to restore her. She eventually gains her real body back, but still a has high levels of spiritual energy as well as having the ability of Astral Projection, that is, to leave her body and project her ghost form at her leisure.
Yurika Nijino (虹野 ゆりか, Nijino Yurika)[6]
Voiced by: Nichika Ōmori[4]
A clumsy magical girl who intends to occupy the room, which contains high levels of magical power, with the intention of defending it from other magical girls who may use such power for evil. She constantly summons magical force fields whenever room 106 residents start engaging each other. Despite this, the residents of room 106 refuse to believe that she is a magical girl, instead considering her a mere otaku who loves cosplay.
Kiriha Kurano (クラノ=キリハ, Kurano Kiriha)[7]
Voiced by: Masumi Tazawa[4]
A well-endowed descendant of the Earth People, who moved underground during centuries past, and a member of the Kurano clan, a family of oracles and spellmasters, who claims that she needs to rebuild a shrine on the room's location and use the etheric energy gathered by it to generate weapons and launch an invasion against the people on the surface. It is later revealed that the Kurano clan wants to make peace, and she is actually doing her best to delay the invasion. She eventually succeeded as the Kurano clan restored its political power before the invasion can actually take place.
Theiamillis Gre Fortorthe (ティアミリス・グレ・フォルトーゼ, Tiamirisu Gure Forutōze)[8]
Voiced by: Maria Naganawa[4]
While her full name is Theiamillis Gre Mastir Sagurada von Forthorthe, her name is often shortened to Theia, or called Tulip. An intergalactic alien princess from a planet named Fortorthe and armed with pulse lasers and cannons. Theia is given the task of capturing a spot in intergalactic space in order to prove her worthiness as a successor to the throne. For the first time ever the random spot chosen by the computer was on an inhabited planet, namely room 106. This means she also has to get the allegiance of the inhabitants, i.e Kōtarō. She is fond of a Fortorthe legend known as the Blue Knight, and named her spaceship and battle armor after him. She later granted the armor to Kōtarō, along with her personal sword, Saguratin.
Ruthkhania Nye Pardomshiha (ルースカニア・ナイ・パルドムシーハ, Rūsukania Nai Parudomushīha)[9]
Voiced by: Saori Hayami[4]
Theia's servant. Ruth often gives useful advice to her master. After an incident where Kōtarō, in his sleep, mistook her for a rhinoceros beetle, she flies into a rage whenever she sees one.

Harumi Sakuraba (桜庭 晴海, Sakuraba Harumi)[10]
Voiced by: Megumi Takamoto[4]
Coming from a wealthy family, she is the kind and well-mannered president of the school knitting club and the only other member besides Kōtarō. Her closeness with him is a constant source of jealousy for the girls living with him, She has feelings for Kotaro.
Shizuka Kasagi (笠置 静香, Kasagi Shizuka)[11]
Voiced by: Aya Suzaki[4]
Landlady of the Corona House, home of Room 106, and a high school girl. She accepts the need of the room 106 residents to compete over it, but forces them to keep the competition peaceful and normal. She's more than a match for the invaders. Shizuka is friendly, respectful and easy to get along with. Shizuka is strongly protective of her family's apartment since both of her parents death. Along with taking great care of it, she will become enraged whenever it is damaged.

Shizuka is the current host of the Fire Dragon Emperor Alunaya. When his power leaks out, it would strengthen Shizuka's already strong body. This is the reason why she could overpowered all of the invaders the day they met despite their own powers. Even without using Alunaya powers, Shizuka is a master martial artist that puts her in the same league as the invader girls.She is currently a member of the Satomi Knights as a Martial Artist.

The Satomi Knights (サトミ騎士団, Satomi Kishidan) is a band of knights created by Koutarou Satomi serving under princess Theiamillis Gre Forthorthe.

Satomi Knights member uniforms were designed somewhat resembling of Koutarou's armor, but the design in its entirety is closer to a school uniform. The colors were blue and white, based on the Blue Knight and Alaia, and then each person's personal color was added in.

Voiced by: Yukari Tamura
Often called Clan, Clariossa Daora Forthorthe is the Second Princess of the Forthorthe Royal family. As such, she is a constant rival and enemy to Theia, even more so given the fact that their families, the Mastir (Theia) and Schweiger (Clan) never got along well in the first place. Originally appearing as an enemy intending to get rid of Theia so as to make her fail her task, but after the events that took place in the past in Forthorthe with Koutarou (after Volume 7, with the story being explained in Volume 7.5 and 8.5), she becomes quite close with Koutarou and decides to rather make Koutarou her vassal, and starts to care less about the throne. From then on, rather than resorting to underhanded tactics, she decides to fight Theia fair and square for the rights to Throne, while in reality caring much more about simply having and making Koutarou her vassal.
She is not only very intelligent, but also a very smart scientist, having created most of the equipment and weapons she uses herself.
Aika Maki (藍華真希, Aika Maki)
Voiced by: Akari Kitō
A magical girl part of the organisation called Darkness Rainbow, she is an enemy of Yurika, as the two organisations Darkness Rainbow and Rainbow Heart are enemies of each other. Appearing as an enemy, and being the main villain of Volume 5, she later on becomes very friendly with Koutarou after he saved her life (Volume 8). From then on, she sees Koutarou not as an enemy, but as a close friend who she does not wish to harm. While still part of Darkness Rainbow, eventually she decides to leave them and live on simply as Aika Maki, and not a member of Darkness Rainbow (Volume 12).
