The next day

With the battle being over, Everyone returned to their respective homes. Y/n and his girls going back to the mansion and Shido with Tohka and Yoshino returning to their house.

Back to Shido

Itsuka Shido, the sealer of spirits was sleeping deeply, the bashing of the battles making him rather exhausted even though his wounds healed up due to his sister's ability sealed in him.

"Kyaaa!"

Shido's eyes snapped open at the high-pitch scream and he quickly got out of the bed and started running, just to accidentally bump into something and fall down.

"Ugh...My head's feeling dizzy." Shido rubs his head in pain and dizziness.

"Shin, are you alright?" Shido heard the voice from below him and realized that the thing he fell on was Reine herself.

"*embarrassed* S-Sorry! I am getting off."
He quickly scrambles off Reine and stands up, Reine also standing up and adjusting herself. She fixes her glass and speaks in her normal tone-

"Don't worry about it much. Yoshino just slipped and fell a bit, she's not hurt though."

Shido: "sighs Oh thanks. I was almost scared that something bad has happened. How is Tohka by the way?" Shido asked the last part with visible concern.

"Well, she's recovered consciousness." Reine takes a deep breath, before continuing. "She was hit a lot by G/n during her fight with him. her ribcage, spine and limbs were partially fractured. Although the wounds have been healed thanks to her own spirit power and Ratatoskr's medical realizer technology, she's left in quite the trauma. I would suggest you take her out on a deep to help her recover mentally once she's fine to leave."

"I will" Shido gritted his teeth, he doesn't know what to say about this but it was his fault, he failed to save her.

As that thought, a memory assaulted his mind, words of the now-gone Y/n's brother wherever he came from.

"It's fine, unc. You are you and I am me. With all that plot armor and pacifist persona, you would've gone it all smoothly but me and my bro are all anti-MC level threats so you're cooked...Deep Fried even, lol. Go touch some grass and get good, You being a real life dating simulator guy is not just cringe, but weird as fuck."

" Am I endangering them? Am I...hurting them by making them weak? I..I don't know what to do. Ever since I met Y/n and later his brother, everything's turned upside down."

"You shouldn't think of it that way, Shin." Shido snapped out of his haze, realization hitting him that he spoke the words out loud. "But..Reine, what can I even do? They are much more stronger and intelligent than any other spirits and they even know what I might try to do. Both times during my encounter with Y/n and his brother, I....could do nothing but watch. While Tohka and Yoshino fought. Even though I was able to use Sandalphon but it wasn't enough."

"Shin" Reine puts her right arm on Shido's shoulder, "You aren't strong, so you can't protect everyone. But this...this is something only you can do, so you must try. You shouldn't give up."

I don't know what they mean but I know I can't stop, I will not stop...No matter what." With newfound determination for Saving the world, Shido Itsuka resumed his duties of sealing spirits and saving them, as the words of these sibling duo will only make him question himself and nothing more.

Back in Y/n's Mansion

"*opening eyes* Uh, its morning."
