A nineteen year old freshman student at K University, Kaoru Satou finds a house to rent a room from the landlord so he can focus on his education. Unfortunately, the female tenants that live there have differing opinions on letting a man live with them! Can Kaoru make it work?
Moving to Tokyo so that he can attend freshman classes at the prestigious K University, nineteen year old Kaoru Satou manages to find a room at one of the houses in town to rent so that he has a decent place to live without breaking the bank on expensive apartments. However, the house is owned by the pervert-hating Yoshino Murakami and is occupied by only female tenants! When Kaoru makes several accidental blunders (of the perverted nature), he finds himself banished to a old tent out in the garden while Yoshino forces him to find residence elsewhere, having thought that he was going to be a female tenant who was moving in because of his name. Can Kaoru earn his way back into the house and into his rented room? Or will he be given the cold shoulder and be forced to go elsewhere?
Kaoru Satou was originally created by Miyano Kintarou for use within the Ikenai Roomshare manga. It is not known as to what inspired his creation.
Apart from losing his virginity and becoming more confident with women after his experiences with the women at the house, Kaoru does not evolve much as a character in the duration of the manga.
It is a clear, beautiful day in the residential neighborhoods of Tokyo, Japan when nineteen year old Kaoru Satou finally finds the correct address to the house that he has rented out a room from so that he can have a place to stay while he focuses on his freshman classes at K University. Sightly surprised that the building is older that he was originally expecting, Kaoru feels slightly nervous and excited at the same time, looking forward to meeting his new roommates inside. Visions of cool, awesome male roommates who would take him under their wing and have him participate in various activities with them fills his head as he opens the front gate and steps into the yard. He has hardly started walking across the yard towards the house when the sight of a large man messing around with an outdoor laundry rack catches his attention. Thinking that this man is the landlord that he is renting a room from, Kaoru introduces himself to the preoccupied man. Kaoru does not realize it, but the man before him is nothing more than a perverted panty thief, and the man locks up in shock since he has been caught stealing various panties from the laundry rack. Making a hasty escape, the panty thief hastily climbs over the wooden fence and runs off, several pairs of panties scattering onto the ground around the fence after being shaken loose from his stash bag. Much to his surprise, something lands on the top of Kaoru's head while he stares in mild confusion at where the thief had jumped over the fence. Grabbing the mystery object off of his head, Kaoru is surprised to find that it was one of the pairs of panties that the thief had jarred loose from his bag in his hasty escape, and it is striped in color complete with a small bow on the front. Looking at the stripped panties in his hands in slight confusion, the sound of approaching footsteps signals the arrival of several people from the house he will soon be living in. Holding a baseball bat, the pervert-hating Yoshino Murakami and one of the female tenants confront the surprised Kaoru, who has now been put into a sticky situation for the panties in his hands just happens to belong to the enraged Yoshino. Believing that he is the panty thief that has been stealing all of their panties off of the laundry rack, she yells "You underwear thief!" at him briefly before smashing him on the head with her baseball bat, knocking him out cold.
A short while later, Kaoru finds himself inside of the house at the living room table, with the frustrated Yoshino and nervous Rin Nonaka watching him. Once Kaoru has the chance to explain to Yoshino that he is the one who applied for the room at the house, she freaks out due to the fact that she approved his application to rent one of her rooms because she thought that he was a girl (due to his name). Turning to the mow-panicking Rin, she is stunned to find out that Rin had left out one key piece of information on the application form when she had posted it, the "Girls Only" part. Slamming her hands down onto the table, Yoshino decides that since she has three girls already living in the house, she can not allow Kaoru to have the room he was going to live in, afraid that he would unleash havoc upon the house due to her worrying that he is nothing but a perverted monster. Feeling unfairly judged by her and not wanting to be thrown out of the house before he even has the chance to move in properly, Kaoru jumps to his feet, begging her to give him a chance since she has wrongly associated him as a pervert. Unfortunately, Kaoru's right knee makes contact with the table when he jumps to his feet, causing him to fall forward towards Yoshino. Reaching out with his hands trying to grab onto something to stop himself from smashing down onto the table, his right hand accidentally grabs Yoshino's skirt, pulling it down past her knees as he manages to catch himself with his left hand, preventing himself from crashing onto the table. Locking up in shock, Kaoru realizes what terrible thing that he has just done as his eyes lock upon the white panties that the stunned Yoshino was wearing under her plaid skirt. Enraged beyond all reason and now convinced that he is indeed a true pervert, Yoshino goes nuts and unleashes her fury upon the panicking Kaoru, who's hasty apologies to her go ignored as she beats him up.
Kaoru finds himself looking at his handiwork outside, having just finished pitching the tent that Rin had given him out in the side garden on the property. Earlier, Yoshino accepted some of the blame for what had happened, but since she is now convinced that he will take advantage of them sexually, she has banished him to live out in the garden for a week so that he can find somewhere new to live. Trying to reason with her and fix what had been accidentally done, Kaoru fails to get her to change her mind, since she is now dead set on seeing him find somewhere else to live. Bummed that his first day in Tokyo has resulted in him being left "half-homeless" and that there is little chance that he will find another place to stay at on such short notice, Kaoru considers this day to be nothing short of an epic failure.
Later that evening, with Kaoru shivering in his blankets within the tent outside of the house in the frigid cold, the other female tenant that rents a room at the house finally arrives back home. Heavily intoxicated from the many drinks that she had consumed at the local bars, Yako Takeshita staggers into the house, much to the irritation of Yoshino and the disgust of Rin. Once filled in about the events involving Kaoru earlier in the day while she was off at work, Yako takes immediate interest in the fact that there is a man around the property, comparing it to having a watchdog for the house. When both Yoshino and Rin head off to do various chores/things around the house, the hammered Yako decides to head outside to personally "meet" with Kaoru, who finds himself unable to fall asleep due to the extreme cold and the constant shivering that his body is experiencing. The sound of the tent's zipper being unzipped catches his attention, and before he knows it, Yako walks into his tent, introducing herself as Kaoru takes notice of the strong odor of alcohol that followed her into the tent. After some short conversation, the drunken Yako takes notice of the growing bulge in his pants, which Kaoru has failed to cover up and hide from her due to the fact that he was too busy staring at her large, ample bust. Amused by his arousal and allowing the alcohol to take control of her thoughts, Yako proceeds to unzip his pants and before Kaoru knows it, she is toying with his genitals, taking great interest in it's massive size. Standing up, Yako turns her body around and lowers her rear end down so that it comes within inches of his face, slowly pulling up her skirt to reveal her panties to the flabbergasted Kaoru, who is blown away by what is happening. Telling him that this is a "reward" for chasing away the panty thief who had been stealing their undergarments, Yako positions herself so that he can perform oral stimulation to her vagina while she turns her attention to giving him a sloppy oral session with her mouth.
After several minutes, Yako is overcome with the passion and ecstasy from the stimulation his tongue is giving her, and is unable to wait any longer to have proper sex. Positioning herself over his lower half, Yako slowly lowers herself onto him, effectively taking away his virginity as the dumbfounded Kaoru loses himself to the heat of the moment, unable to restrain himself as they begin having sex together. For the next few minutes, Kaoru toys with and sucks on her stiff nipples as Yako loses whatever control of herself that she had and goes into overdrive, moving her hips in such a way that they both race towards their sexual limits. Unable to stop himself from reaching orgasmic climax, Kaoru reaches his limit and with a mighty thrust that sends waves of pleasure racing through Yako's body, he unleashes his thick seed deep inside of her. Lost in the pleasure that her body is experiencing and succumbing to the tiredness that she had been suffering from earlier, Yako swiftly falls asleep inside of the tent, stealing away his thin blanket to keep warm with as the shell-shocked Kaoru sits against the far side of the tent, a blank look on his face as he tries to piece together what had just happened. Panicking, Kaoru is worried that the other two females in the house will discover what had just happened and Yoshino might just go off the deep end with her fury in order to get back at him for doing such a perverted thing to one of the tenants under her roof.
Unknown to both himself and the slumbering Yako is that Rin had headed outside with several rice balls on a plate in the hopes of giving Kaoru a decent meal since he was stuck out in the cold. Realizing what has just happened inside of the tent between Kaoru and Yako, Rin goes into a state of shock, dropping one of the rice balls onto the ground as she locks up, her eyes open wide in shock.
