*For those who don't know, I recently created my own OC/Mascot, Izumi. So, guess what that means....time for her to meet/beat the harem. I hope you all enjoy this chapter.*

It was a peaceful day in Chaldea. For once, there were no Singularities to resolve, no events to clear, and no grinding that needed to be done. It was a day where everyone could sit back and relax. For example, MHX, MHXX, MHX Alter, Hokusai, and Summer Jalter were spending the day just reading manga under black coffee table. Atalanta, Chiron, Scathach, and Li Shuwen were training in the simulation room. Emiya and Emiya Alter were frantically trying to feed the Saberfaces in the cafeteria who decided to spend their day off binge eating.

Finally, Lancer Fionn Mac Cumhaill and Orion decided to try to peep on the female staff's shower. The perverts of Chaldea were waiting for a day where everyone seemed to have dropped their guards. Nothing was going to stop them from getting their freak on....at least until a large chunk of the wall broke free and slammed the perverted against the opposite wall. The last thing they saw before blacking out was a white haired woman in an full black suit glare at them before running off. Chaldea's alarm immediately went off screaming: Intrudet Alert!!! Intruder Alter!!! An unknown figure has broken into the faculty!!! Prepare countermeasures! All servants prepare for battle!!!

In his room, Ryan looked up from his Nintendo Switch as he and Tomoe Gozen had been replaying Fire Emblem Three Houses when the alarm went off. Jalter groaned in anger as she put down her tea that Mashu had made her while they watched the brown haired boy played his game.

"Are you kidding?! Can we not have one day where something doesn't go wrong?!," Avenger exclaimed angrily.

"I agree. I was looking forward to playing some games with Tomoe.," Ryan admitted.

"Really? Thank you, Master.," Archer of Inferno said with a slight blush on her face.

"Could you two not flirt in front of me?," the fallen holy maiden stated coldly. "It just makes me want to burn you both."

"Umm....should we worry about the intruder?," Mashu asked nervously.

Ryan shook his head as he went back to playing his game. "No. With all the servants I've summoned in the past three years, there's no way anyone can get pas-"

Red Alert!!! Red Alter!!! The intruder is on the move. They have already taken down Fionn, Orion, Astolfo, Kiyohime, Raikou, and Shiki!!!They seem to be heading towards Ryan's room! Protect him at all cos—-oh no!!! They in here!! Someone he—-Arghh!!!

"Ok....now we should be worried.," the master of Chaldea said as the door to his room suddenly opened as Gudako walked in with Saber Alter with a ton of snacks. "What are you two doing?! Chaldea is under attack!!"

Gudako just ignored the boy as she walked up to the boy. "Yeah yeah...it's probably just a drill. Besides, the servants that the intruder has taken down are the weaker ones....the heavy hitters like Gilgamesh, Scathach, Hercules, and Merlin should taken them down long before they get here. Now let's ha—"

That's when the wall was bursted open as ruble flew toward the group. Jalter, Salter, and Tomoe destroyed the pieces of rubble that flew towards them while Mashu summoned her shield and defended the two master just the intruder of Chaldea walked through the wreckage. They were a young woman with white hair and bright red eyes wearing a full black suit. An aura of pure anger seemed to radiate off her as she scanned the room until she locked eyes with Ryan. She had finally found him...

"There you are!!!," the white haired girl yelled. "Do you have any idea how long it took me to find you?! Three fucking years!!! You have no idea what it took to find this place! I thought you were being tortured......but no!!! Here you are living the good life surrounded by beautiful women!!! I have half the mind to kill you right now!!!"

"Just try it bitch!," Jeanne Alter said with a smirk. "I would love to see you try. No one touches my man and gets away with it!"

"Touch.," Gudako said as she poked Ryan causing the group turned towards her. "What? I thought it would be funny."

"Ok....let's just pretend that didn't happen.," the intruder said turning her attention back to Ryan. "Now hand over my boss and no one else needs to get hurt."

"We'll never give you Senpai! We would rather—," Mashu started to say before she realized something. "Wait did you just Senpai is your boss?"

"Of course she did. She's my bodyguard, Izumi.," Ryan said causing the other girls' jaws to drop.

"What?!!!!!"

XXXXXX

So...it turns out that Izumi was Ryan's bodyguard who he hired three years ago to keep him safe from yanderes. However, when Chaldea had brought the brown haired boy to become one of their masters during the Incineration of Humanity incident, Izumi had no idea where he had gone as he had just had disappeared one day. So, she spent the next three years searching for him. It took a lot of effort and a cracking a few heads, but she finally figured out that he was at Chaldea.

"Wow....we had no idea that you had been searching for him.," Mashu said as some staff was currently working on fixing the damages to the facility caused by Izumi's rampage.

"I'm more impressed that you found us.," Da Vinci admitted.

"Well...it did take me three years to do it.," Izumi said with a slight smile. "Sorry about the mess...I thought my boss was in danger."

"It's ok! We should have know people who knew Senpai would come looking for him.," Mashu stared returning Izumi's smile with her own. "Hold on...Senpai. Why did you never mention her?"

Ryan nervously looked away from the group. "I might have forgotten to mention her."

With that, the brown haired boy immediately had his foot crushed by his angry bodyguard. "What do you mean you forgot to mention me?! You've been here for three years and you never mentioned me once?!"

"In my defense, I had other things on my mind like prevent the Incineration of Humanity and defeating the remaining Demon God Pillars!," Ryan exclaimed. "Besides, I thought you would got another job when I disappeared!"

"Well...that was an option, but I wasn't willing to do nothing while everyone else thought you were dead.," Izumi stated. "I was going to find you no matter what!"

"Wow...that's true devotion, but you don't need to worry about Senpai anymore. He's got me now to protect him.," Mashu said with a smirk.

"Oh no you don't! Protecting the Boss is my job!," the white haired girl exclaimed. "I was here first! So beat it, eggplant girl!"

Mashu's right eye twitched in anger. "I'm sorry...what did you just call me?! I've been doing your job for three years, you slacker!!!"

"That's because you all kidnapped him!," Izumi yelled back as sparks flew between the bodyguard and the kouhai.

The two protectors were about to throw down when Da Vinci got in between them. "Now hold on you two...you both want to keep Ryan safe, right?"

The duo looked at each other for a moment they said, "Yes..."

"Then why don't you two work together?," the Caster class servant suggested. "We would be happy to have Izumi join the staff here and wit her here, Ryan will much safer than he has been these past three years. So, what do you say?"

The girls sighed as they shook hands. "Fine...we'll work together."

"Good....now, I have to go repair the wall Izumi broke when she first arrived.," the inventor said as she began walked off. "It letting a terrible draft in."

Once the caster was out sight, Izumi quickly threw the other girls out of the room as she said, "I need to talk the Boss real fast. You all can wait outside until we're finished."

They all just say there for a moment before Jalter said, "Did she just kick us out of the room?"

Meanwhile, Ryan gulped nervously as Izumi turned towards him a devious smirk. "Umm...Izumi? What are you doing?"

"Oh nothing.," the white haired girl said as she walked up to her employer before suddenly pinning him onto his bed. "I just need to tell you something."

"Tell me what?," the young man asked as the beautiful woman leaned down next to him as close as she could that her breasts were pressing against his chest.

"I need to tell you that....," the bodyguard whispered raising her head as she glared at the boy. "You owe me three years worth of pay."

Ryan's heart immediately dropped. "What?"

"Oh don't worry. You don't have to pay me with money. I accept cash, ,ice cream, and....," Izumi stars as she moved her hand down until she firmly grabbed her boss's manhood. "This."

Let's just say with Izumi's arrival, Chaldea had gotten even more crazier than ever before. After all, She had finally found her man and wasn't ever going lose him again.

With that, Izumi is part if HIMMH Canon, but don't worry, she won't appear in every chapter. However, if you want to know more about her, let me know in the comments.
