Sitri Smart

In the famous party Strange Grief in Nageki no Bourei wa Intai shitai, Sitri Smart is the terrifyingly smart alchemist. She is Liz's younger sister and the group's ultimate sweet-faced mad scientist. At first glance, she looks like a completely harmless and kind supporting character. But she's really a ruthless genius who makes illegal potions and scary bioweapons without even thinking about it to help her childhood friend Krai. The funniest part of the whole show is when she smiles sweetly while planning terrible things.

In terms of looks, Sitri is the perfect example of a top-tier waifu who lies. She has soft eyes, short pink hair, and always wears a very fancy blue and white scholar coat. Her simple, elegant design gives her all the sweet oneesan energy she needs. She is a real threat. Fans go crazy over her scary yandere personality. She will gladly dissolve whole enemy syndicates in acid just because they bothered Krai a little bit. It's a well-known fact that she would casually take out her pet slime to get rid of bodies while keeping a completely innocent blush on her face. We love her so much because she has the look of a pure, gentle healer and the mind of a criminal mastermind who is completely out of control.

Sitri wallpapers are amazing because they look so good but are actually very deceptive. Artists love to draw her with glowing, colorful potion bottles and a shadowy figure hiding behind her cute smile. There is a lot of fan art of her happily hugging Krai or posing with her deadly pet slimes in a classy way. A Sitri wallpaper is exactly what you need if you want a background that perfectly captures the sweet waifu energy and the total dangerous psychopath vibes.
