Notes:

Spent over 3 hours making this ultra high-res version of this pic by Kimagure Ringo: https://www.pixiv.net/member_illust.php?mode=medium&illust_id=14136104

Literally 100% worth it.

Used waifu2x and https://online.photoscissors.com to make it.

Download full (and slightly fixed) 2000×1500 version of the image here: https://files.catbox.moe/p9k1ws.png

And here's a wallpaper version I made: https://files.catbox.moe/0l916n.png
