Koshi Anko

In the funny anime Shikanoko Nokonoko Koshitantan, Koshi Anko is Koshitan's crazy younger sister. She may look like a normal middle school student, but in the show, she is a complete and utter siscon. She is completely in love with her older sister Torako. This makes her the best competitor for Nokotan, of course. She is always coming up with plans to get rid of the crazy deer girl who had the nerve to take her precious onee-chan's attention. Her extreme jealousy and crazy trap-setting make her one of the funniest people on the show.

Anko has beautiful blonde hair tied in cute twin tails and bright blue eyes, which she got from her family. Most of the time, you'll see her in her classic sailor uniform, which she wears while coming up with her next crazy plan. She is the perfect example of the extreme yandere waifu archetype, but it's all for laughs. When she's with her sister, she acts like the sweetest, most innocent angel ever. But as soon as Torako looks away, Anko's face drops into a terrifyingly cold glare that is aimed straight at Nokotan. Fans go crazy over this huge gap moe. It's hilarious to see a cute middle schooler pull out ridiculous weapons to defend her sister's honor. Her complete commitment to being a troublemaker makes her a fan favorite who will never be forgotten.

Anko's wallpapers are full of fun and chaotic energy. Artists love to draw her two sides, usually splitting the canvas between her angelic smile and her scary yandere glare. There is a lot of funny fanart of her setting crazy traps or fighting Nokotan over a piece of deer cracker. Her bright blonde look makes for very clean backgrounds on your desktop. If you want a lock screen that shows the best of anime sibling rivalry, her gallery is a real gold mine.
