Existence of Other Systems

"I am home." Akira exclaimed opening the door, and replaced his shoes with sandals.

"Welcome back."

Yotsuba came to greet her little brother with a voice full of vitality. Approaching his little brother, she took the schoolbag from his little brother. She acts like a wife, welcoming her husband home from work.

After putting on their sandals, Akira and Yotsuba walked to the living room.

In the living room, Ichika, Miku, and Itsuki are sitting on the sofa watching a drama on TV. While Nino, helping mother prepare the evening in the kitchen.

Ichika: "Welcome back Akira-chan~"

Miku: "You came home later than usual."

Itsuki: "Are basketball club activities very busy?"

Unbuttoning his shirt one by one, Akira lied without batting an eye:

"Um, the training is very busy, I want to take a shower first, my body is sweating."

"Here are towels, and a change of clothes."

Yotsuba, who had previously gone to Akira's room to put down his school bag, had returned with a towel, and his little brother's clothes in his hand.

"Thank you, Yotsuba-Nee, I always make trouble for you." Akira said.

"What is Akira talking about, Onee-chan never once thought Akira was a bother." Yotsuba shook her head.

Hearing Yotsuba's answer, Akira smiled faintly and, placing a towel over his shoulder, he walked to the bathroom.

*Jiiii*

After Akira left, Yotsuba noticed the sharp looks Ichika, Miku, and Itsuki, were giving her.

"W-What? Why are you all staring at me like that?" Yotsuba asked nervously.

Touching his lips with his index finger, Ichika said with a smile:

"Am I the only one who feels the Yotsuba's behavior is like a wife serving her husband after work?"

"Hah? Don't talk nonsense, Ichika!" Yotsuba's face flushed with embarrassment.

Holding the blue headphones hanging around her neck, Miku nodded, and said:

"Ichika is right, I also feel that Yotsuba treats Akira too much."

Itsuki ate the potato chips, his ahoge hair swaying left, and right, showing she was in a good mood, and said:

"Yotsuba, don't cross the line that shouldn't be crossed."

"Mou~ Even Itsuki too, I'm not what you think. I will help Nino, and mother in the kitchen."

Seeing Ichika's, and Miku's, looks of disbelief. Yotsuba, whose face was bright red, turned around, and went to the kitchen.

Miku, and Itsuki returned to watching TV after teasing the Yotsuba, neither of them noticing the dark glint in Ichika's eyes before returning to normal.

...

Akira took a bath for 10 minutes, wearing the casual clothes Yotsuba prepared, he walked out of the bathroom.

After drying the towels on the balcony, Akira sat on the sofa with his older sister, and watched TV.

At 6.40 pm, their father, Nakano Maruo, came home.

"I'm back."

Itsuki: "Welcome back, father."

Miku: "Welcome back, father."

Ichika: "Welcome back, father."

Akira: "Welcome back, father."

Seeing his children greet him, Maruo nodded his head, and walked into his room.

"As always, father isn't smiling at all." Ichika said suddenly while playing with the hair beside his ear.

"I've never seen father smile." Miku said, she was used to seeing her father's flat expression.

"I've seen father smile once." Itsuki gives out information that shocks Ichika, and Miku.

Ichika: "Is that true? Itsuki isn't lying, right?"

Miku: "When? Why didn't I know?"

Itsuki looked at his little brother who was playing on his cell phone, and said:

"It happened a long time ago, it was when father was holding baby Akira, I happened to see father smiling."

"Oh, I see." Ichika nodded in understanding.

Miku bit her lower lip, and didn't say anything.

The quintuplet girls know that Maruo is not their biological father, only Akira is Maruo's biological child.

Even though Maruo never treated quintuplet girls unfairly, he subconsciously treated Akira better than quintuplet girls.

"Dinner is ready, wash your hands before eating."

Nino came from the kitchen, she was still wearing his apron, and his hair was tied in a ponytail, which complimented his white neck.

Turning off the TV, Akira along with Ichika, Miku, and Itsuki washed their hands in the bathroom before heading to the dining room.

Arriving at the dining hall, Itsuki opened his eyes wide, and a bit of drool flowed down his mouth.

"Sukiyaki!"

"Itsuki-Nee, you are drooling." Akira reminds.

"Itsuki is so dirty." Nino scoffed.

"That's what Itsuki is like." Miku nodded.

"This is not on purpose." Itsuki replied, embarrassed, and wiped his mouth.

Akira, and the quintuplet girls sat on their respective seats, Rena, and Maruo sat side by side.

Everyone cupped their hands in front of their chests, and said a sentence before eating.

"Ittadakimasu." 8x

After saying that, the fastest person was Itsuki, she sliced beef in the iron pot on the stove, and placed it on his plate.

"Itsuki, eat slowly, it's not good for girls to eat in a hurry."

Rena warned Itsuki, who was eating fast.

"I know, mom." Itsuki replied sadly after being scolded by his mother, and his ahoge withered slightly.

Akira put beef in his mouth, looked at his mother, and said :

"It's delicious, mom's food is the best."

Hearing her son's praise, Rena smiled happily, and said:

"Mom is glad Akira likes it, eat more, you need a lot of nutrition for growth."

"Um." Akira nodded.

Suddenly, the screen panel that only he could see appeared in red.

[Ding! Warning!]

[Detected a system called Super Dimensional Guild is gathering Host information]

[Anime's Myriad Sign-in System takes countermeasures....]

[Ding! The prevention system failed...]

[Ding! Initiating the protocol hides the strongest ability that the Host has...]

[Ding! The protection protocol succes!]

"Hah?" Akira was stunned to see this all.

"Akira-chan?" Ichika called out to Akira, who looked lost in thought.

"Nothing, I just thought of something." Akira said lightly, he would ask the system after dinner.

...

Dinner lasted 20 minutes, Ichika, Miku, and Itsuki helped wash the dishes, while Nino, and Yotsuba watched TV.

Among the quintuplet girls, only Nino and Yotsuba can cook and do other housework.

To be fair, Rena told Ichika, Miku, and Itsuki, who didn't help with the cooking, to wash the dishes after eating.

"Would you like some oranges, Akira?" Asked Yotsuba who was peeling an orange.

"No, thanks Yotsuba-Nee, I want to go back to my room first." Akira refused.

"Why the rush, let's watch TV first." Nino patted the chair next to her.

"Sorry Nino-Nee, today Sensei gave a lot of homework, I want to do everything before going to bed." Akira gave a logical reason.

Crossing his white, smooth legs, Nino said: "I see, you are very diligent, Akira, no wonder you have always been an honor student."

After chatting briefly with his two older sisters, Akira got up from the couch, and walked up the stairs to the second floor.

Pushing his bedroom door open, Akira entered the room, then he locked the door to prevent anyone from entering.

Sitting on the bed, Akira's cheerful expression was replaced by an unprecedentedly serious one.

"System, what happened earlier?"
