Kayo sits at the small kitchen table and taps her fingers idly. It’s been two weeks since Satoru left and she hasn’t heard a word from him. Sachiko will be returning from her trip tomorrow and she’ll have to inform her that her son is missing. She’s sure she’ll be angry and scold her forever letting him go on such a fool’s quest, and she’d hate to cause her pain, but even still, she can’t bring herself to regret it. Satoru was so sure of himself and that he would come to find this Revival, he seemed so adamant about. She’d never seen him so certain of anything in the time she’s known him. She’s going to miss his company and it’s hard to know that she’ll likely never see him again.
However, she still has her memories, memories of her time with him. Memories of his hard work and dedication to save her in from such a dangerous situation. Memories of how they caught the bad guy all those years later by working together. Yes, she may have lost him in body, but nothing; not the universe or otherwise, can take away her memories of him and all he’s done for her; for all of them. It’s thanks to him that she can even be living today. He’s already given her twelve years of his life, so it’s only fair that she allows Airi to have the rest. She can’t really explain it, but despite what the most logical explanation for the fate of persons missing for over two weeks, she somehow feels that he’s not dead. No, she knows it. He’s alive out there somewhere, but she hopes that he finally found his precious blue butterfly and that it lead him back to his family as he was so sure it would. She has to believe it wasn’t for nothing.
She stands and gathers her things and turns out the lights. She opens the door, locks it and returns the key to the slot. As she stands in the doorway, she looks once more at the inside of the home she’s unlikely to see again. As she shuts the door, she looks up at the sky. It’s clear and filled with stars. Across the sky, she sees something small and blue soar up to the stars and she thinks of Satoru. With a smile; she whispers one final question, hoping it’ll reach him.
“Satoru...did you find it?”
Satoru runs down the street, periodically checking his watch. “Oh man, don’t let me be late!” He turns off to another street and thinks he’s on track, but then he passes a bakery and sees they’ve got melon buns on sale. “Oh, I can’t pass that up, Kayo absolutely loves those.” He decides to stop in, but intends to do so quickly. “Excuse me, I’d like to buy some bread!”
A woman comes out from the back and smiles when she sees Satoru. “Oh, haven’t seen you in a while. Let me guess, melon buns for Kayo right?” She starts to pick them out one by one.”
“Oh, you’re the best Tsubaki-chan! How are you and Watari doing? Well I hope?”
“Yea, we’re fine. Though I had to scold him for looking at another girl too long the other day.”
“I was just admiring her outfit!” Watari calls out from the kitchen and Satoru laughs.
“I’m glad to see you two are in good spirits. I’m off to the school now, wish me luck.”
“Of course. Say hello to that dorky loser for me too would you. Tell him to stop by sometime.”
“Will do, thanks Tsubaki!” He pays and then runs out the door. However, he bumps into someone. “Oh, I’m so sorry. It was my fault for not looking where I was going!”
Someone laughs and he looks up to see it’s Yuzuru. Beside him smiling as well is Kanade. “It’s ok, I’m a doctor. Do be careful though Satoru, and give my best to everyone.” They wave and continue inside the bakery, where they had first met him, as far as they know anyway. He continues his sprint and arrives at the elementary school, as he hears them announcing the start.
“Attention parents, the performance is about to begin. The students will be singing a variety of songs for you today, accompanied by our most revered guests, Kousei and Emi Arima-san!”
There is applause and the kids begin to set up on stage. Looking around Satoru finally spots his targets. Standing in the back row is a woman with long chestnut hair, brown eyes and a warm smile. Beside her is a middle school girl, eager to find her sister on stage. To him, this is the most beautiful sight ever. “Airi, Saori!” They both turn and look at him, their smiles beaming. “Sorry I’m late, but I couldn’t help but pick up a little treat for Kayo. It’s her favorite, melon buns. I figure she might need a good snack to celebrate after the show. I saw everyone too, they say hi. It’s still hard to believe they’d all end up in the same timeline as us though. It’s crazy.”
Airi giggles. “Well, I find it to be sensible. Why wouldn’t they end up in the same timeline as the man who saved them from their turmoil. I mean, that must be fate at work right? You found us again after all. I’m glad you did, but how could you be sure that we’d be your Airi and Saori?”
“Oh, well that’s simple. I told you didn’t I? That I’d find you again? I meant every word.”
“But to figure out that when we died in that other timeline, we’d manifest in this one…it’s nothing short of genius. We could’ve been totally different people if you were wrong.”
“Oh, well that’s simple too. All I had to do was-.”
“Please everyone, take your seats. The show’s about to begin. Please refrain from talking.”
Airi shakes her head, saying they’ll have to finish talking later. Right now it’s all about Kayo and her first performance as a first year elementary student. When Satoru came out the end of that portal, he found himself back in the city where he lived. He knew what he had chosen, but for a moment, he wondered if he’d actually returned to Kayo. However, the blue butterfly continues to flutter and he followed it to his home, looking just as he remembered it. It’s was the home where he lived with Airi once they got married, where she gave birth to Saori and where she would later give birth to their second daughter four years later. After Satoru had explained his entire journey to Airi and the circumstance of having to leave Kayo behind to be with them again, she suggested and Satoru agreed; that they’d name her Kayo. This way, Kayo did exist in this timeline, even if only in name and her memory would also live on with them, even if her memory of Satoru did not. He knew that she’d have Hiromi and Mirai to keep her happy. So that’s why, as he followed that butterfly and walked through the door, he knew before he even saw them that he was home, and so he announced as such. Standing there together, the two smiled with their arms open wide as they said, “Welcome home”. He smiles and he can imagine just what Kayo would ask if she could see him just one more time. Kayo…Yes, I found it. Having served its purpose, his blue butterfly flutters away and he watches as it goes; vowing once more;
Even until the end of time, I’ll continue to search for my little blue butterfly…
…because it’ll always lead me to you.
