Masami was going to die, but Kiriya didn't need to worry at all.
He had spent quite a lot of time in the Training Field, long enough to ascend his body and soul to a higher level.
He had the ability to heal her. He had developed a spell for that reason. Technically, the spell was already finished and could be used immediately. However, it had not yet been tested on living beings. Whether the effect would be as Kiriya desired or not, he is going to test it on Masami directly.
The moon hung overhead. With silent steps, Kiriya appeared inside Masami's dark room. The remaining dim light came from the hallway light shining from under the door.
Masami's chest rose and fell steadily, she looked so deep in her dream and unguarded. Different from the strong impression she showed at all times.
Even though Masami behaved like an adult, she was still an innocent teenager.
This was the first time Kiriya entered a girl's room without their permission, especially when he was already able to feel emotions again. He was nervous.
There was indeed no possibility of being caught, but he did not want to spend a long time in this place.
Without wasting more time, Kiriya raised his hand, a magic circle appeared from his palm, and light enveloped Masami's entire body.
—[Formless].
—[Continue to Omega].
By utilizing [Dreamless], [Digitalization], and also Essence collected by the Dream Nail, Kiriya developed magic that could read and manipulate the souls using magic.
Kiriya named the spell [Soulless].
However, Kiriya did not use Soulless on Masami's soul. Unlike himself who required physical and spiritual strengthening to an extreme point for the Group Chat, Masami only needed to live as a healthy normal human. Having a happy family and dying peacefully in old age was enough for her.
In Masami's condition, only her body suffered damage, while her soul was strong enough to produce regrets to the point that she did not undergo reincarnation directly because of her resentment, much like what is shown in the "Angel Beats". Her soul was strong, Kiriya didn't need to do anything with it. Unfortunately, her body had been injured to the point that inevitably, she ended up passing away.
The soul and the body depend on each other. If one side is too strong, then the other will not be able to hold it—this problem was also what happened to Kiriya when he used [Soulless] in the Training Field in his experiment.
That was why Kiriya created magic capable of reading and manipulating the physical body, [Formless], to match his soul that had reached a higher degree.
As a result, his body also reached the same level.
By that base, [Formless] was actually enough for Masami, but he used a different spell.
[Continue to Omega]. This spell utilized the principles in [Formless] and [Soulless].
In principle, [Continue to Omega] was merely an application of both in one spell.
This spell would read information from the target regarding the quality of the body and soul, when there was an imbalance quality of the body or soul—for example, Masami who was weak on her body—[Continue to Omega] would repair the damage within Masami's body to match the quality of her soul. And finally, the target's body and soul became balanced again. As simple as that.
When the spell finished completing its task, Kiriya used [Formless] to read Masami's physical condition after the treatment.
He had already used [Formless] the first time to read Masami's initial condition as a control, so he already knew which part of the brain was injured and which parts of the body could be repaired.
As a result, the injury had disappeared, and all the organs within her body were healed and returned to the peak of health as if Iwasawa Masami had been reborn. Her health is even better than anyone her age.
A faint smile appeared on Kiriya's face. He activated one more spell for her good sleep.
—[Dreamless].
'Congratulations on your recovery, have a good dream,' Kiriya thought to her before disappearing into the darkness of the night, teleporting away.
***
Masami woke up with a body that felt light and refreshed. She had a pleasant dream last night, though unfortunately it was just a dream. Even so, her mood felt good today.
In the afternoon after his class, Kiriya came to visit like yesterday. Unlike the previous month, Kiriya intended to visit Groza and Masami more often to see how they were doing.
That day they just relaxed together in the living room, enjoying the sunlight coming through the side glass door while watching television.
Kiriya reached for a piece of yokan and ate it in one bite. "Groza, Masami."
"Yes?" Masami replied, snapping out of her daydream after hearing Kiriya's voice.
Groza only turned her head in response.
"How about we go on a vacation?"
"Where are you planning to go?" Groza asked.
"What do you guys think?"
Masami lowered her eyes. "... I'm not sure… I think anywhere is fine."
"I will follow wherever you go."
"..."
Kiriya looked deeply at Groza and Masami. How could they have no desires…?
"Could it be that you two have just been staying at home all this time?"
"Except to buy food ingredients for Masami… yes?" Groza replied.
"I also sometimes go out to the park to practice music," Masami replied after that.
"Other than that?"
The living room fell silent.
"... I see. No wonder then."
One was a war machine who can't eat human food and the other was a runaway teenager who's sole reason to live is for her music. How could they want something more when their previous standard of living could not be compared?
This was Kiriya's fault. He had neglected them too much as if they could take care of themselves.
Of course they could, at least to survive, but Kiriya still felt like a failure as the family head.
Kiriya smiled as best as he could. "... Anyway, we are going on a vacation, wherever it is. At least, we're getting out of these walls."
Kiriya also needed to take a break after the previous mission. He really hadn't rested much just to make preparations against Kibutsuji Muzan, even after that, he was still working to play with his new toy, Dream Nail. Kiriya didn't know about the others, but he hadn't met other important figures in Kanae's world except for the villains.
That was a pity, but what else could be done.
'Before I go visit Mei or Yahiko's world later, I'd better interact with the world. I still don't know what secrets lie in the darkness of this world.'
Yokai, aliens, or even… obsession with spirals… Kiriya had to find out about his own world. He had been too focused on other worlds. This vacation could be an opportunity for him to explore the world more.
"If we go on vacation, should we avoid the sea, for Groza-san?"
Masami's words reminded Kiriya again about Groza's body which could not eat human food yet.
'Of course, naturally Groza and Masami know about each other's secrets. They are friends living under the same roof.' Kiriya smiled, only internally.
"Actually, my skin is sufficient to act as insulation, so interaction with seawater will not affect me," Groza answered Masami with a smile.
"She was not different from a human." Kiriya continued. "What makes her different is she can't eat, that's it."
Since living together, even before Masami went for a check-up at the hospital, the two residents of the house were close enough that Groza revealed her identity as a robot. Kiriya knew since Groza had once asked for permission to reveal her identity. After all, it was difficult to hide the fact that Groza did not eat or drink when Masami was there living with her.
Thankfully she understood personal limit very perfectly. Kiriya didn't bother to explain Groza's origin and she did not ask any words about it.
'I was legally an adult and this house is also under my name, while they…' Kiriya glanced toward Groza and Masami.
Kiriya was not too worried about their illegal state, but sooner or later, there would be a situation where Kiriya had to do something about them.
For Groza, Kiriya was not too worried because he could hide her anytime. Groza was fundamentally Kiriya's property that could be stored in the Item Storage. Of course, Kiriya still gave Groza the opportunity to choose. And he even got a fabricated identification for her before.
Meanwhile, Masami was a living human. There would be situations where she creates relationships with other people and gives her name in the future. Kiriya wants her to learn about the world and experience them for herself, not just caged in this place like Kiriya's pet.
"Masami, do you want to take my name?"
Kiriya turned toward Masami.
"...."
Her face was hidden when she looked down but Kiriya could see her ear had turned redder than her hair.
"Senpai—!? I–is that mean…"
"It's not like that, I'm just going to take you in as a sister, well… I don't really mind if you want to go that far, but my goal is to take custody of you from your parents. I want to adopt you as my family legally."
Nakuru Masami.
That name appeared in Masami's mind. Surely it was not possible that Kiriya would ask her to marry all of a sudden of course, she just didn't expect that Kiriya would even think of giving his family name.
"Of course you don't need to answer now," Kiriya brought her out of her daydream. "And also, changing your last name is optional, I will still adopt you even if you don't want to change your last name."
"... It's okay. I want to, Kiriya-san."
"Alright, then we will visit your parents' house to get their permission—at least formally. Your name is still under Iwasawa."
"I understand."
Kiriya patted the young girl's head.
"In that case, our destination is decided. We will handle Masami's registration into my family."
"Yes, Master."
"Yes, senpai."
But before doing that, Kiriya had to handle the separation of his name from his father's family registry. Should he tell the truth, or make an excuse and hide Masami from his parents…?
'Whatever. I'll just tell them, it's not like I'm gonna be a criminal anyway.'
Whether they agree or not, it's Kiriya's future problem.
———
Masami will not be the part of the harem. Only sister.
Of course I can change my mind later if you don't like it, but become love interest or not, it will not change the story that much.
