Adachi to Shimamura - Volume 3 - Chapter 2.2

Bonus chapter: "Yashiro: The Visitor - Part 4" 

"I have come to receive chocolate", Yachii said, standing before the front door. Like yesterday, she had once again come over to our home. 
"...What?" 
Sis stared at her dumbfounded, and cowering behind her, I did the same. 
"I heard that I could receive chocolate!" she repeated, a bit louder this time, while spinning her arms in the air. I couldn't help but notice the way her eyes sparkled. They were the same colour as her hair and shone with light, literally, not figuratively, although in Yachii's case, that wasn't really all that strange. 
"What are you talking about? Oh, you mean like, Valentine's Day?" 
"Yes, that. That exactly", Yachii nodded twice. For some reason, the movements of her head felt extremely light to me. 
It was as if she was just nodding for the sake of it. 
"As far as dates as concerned, I'm pretty sure that Setsubun is the closest holiday." 
"Alright, let's go with that then." 
There was a wide grin on Yachii's face as she said this. Could you really switch them up like that? Sis seemed quite astonished as well. 
"I wonder, just who did you hear all of this from? Anyway, I think we might have some chocolate in the fridge", Sis said while turning to look over her shoulder. She then began making her way towards the kitchen, but not before placing her hand on Yachii's head—now jumping up and down in place—and pushing her down. 
"Stay put, okay?" 
"Okay!" Yachii exclaimed, her back straightened out. Apparently satisfied with this, Sis turned around and, for real this time, left. 
Feeling her eyes on me, I turned to face Yachii. 
She hadn't "stayed put" for even five seconds. Her large eyes quickly rotated to point at me. 
Her pretty eyes, so pretty that whenever I stared at them, whenever she stared at me, I found my heart pounding in my chest. 
"You too, Shou. Give me chocolate." 
"What?" 
Forming a bowl with her hands, Yachii stuck them out to me. It was pretty lavish of her to demand chocolate from even me. 
Hmm, I pondered to myself while staring at her tiny hands. I hadn't really noticed it before, but even her fingernails were faintly blue. 
Was it, nail polish? 
"Sure, but only if you give me some too." 
"Why?" Yachii tilted her head, seeming genuinely puzzled. It appeared that she'd understood it as a day when you'd simply get to receive it unilaterally. 
Really, who had she heard all this from? 
"Because that's how Valentine's Day works." 
"Really?" 
"Yep. Probably." 

I spun my arms around. Yachii did the same. Round and round. 
"Well, in that case, I'll prepare some for the next time we meet." 
"Next time?" 
I had no clue when that was going to be. I didn't even know where Yachii lived. 
If I were to try looking for her, I'd never find her. On the other hand, whenever Yachii felt like it, it only took mere seconds and poof, she was already by my side. 
She wasn't actually a fairy, was she? 
The strand of hair she'd tied around my finger continued giving off faint blue light. 
I often found my eyes being drawn to it before I went to bed, and each time, it felt difficult to look away. 
"Damn, it's so cold", Sis grumbled, having returned from the kitchen. She was easily the member of our family the most affected by cold. 
According to Mom, it was a case of her not having enough guts. I definitely got what she meant. 
"We got some macadamia nuts left." 
The box Sis had brought with her was a souvenir from overseas she'd received last month. 
"Ooh, this will do nicely", Yachii said before grabbing the box, almost as if jumping at it. She then proceeded to hold it above her head with both hands. I could practically hear her yelling something to the effect of "I got it!". 
"Next time, I'll give you something in return, Shimamura." 
"Huh? No, wait, you're not planning on taking all of them, are you?" 
"Wheee!" 
Not bothering to listen to her in the slightest, Yachii ran off. 
Her feet moved back and forth rapidly as her hands held the box high. She seemed genuinely filled with joy. 
"Oh my... Well, whatever. I don't think that there were more than three left anyway." 
Judging from the way her body was shaking, the cold appeared to be of a bigger concern to Sis. 
Next time, huh? I'd need to prepare something for her as well, wouldn't I? 
"It feels like everyone wants chocolate", Sis grumbled while staring at Yachii as she disappeared into the distance. 
"Everyone?" 
Puzzled, I tilted my head, which prompted her to pat it. 
"You want it too?" 
"I might consider it, depending on what you get me. Ehehe", I stated proudly, my hands on my hips. 
She then poked my stomach with her finger, nearly causing me to choke. 
Ehehehe.
