Dusk
Dusk is probably the most relatable god-tier being in Arknights. She is one of the famous Sui siblings from Yan and works as an incredibly strong Splash Caster for Rhodes Island. But let us put aside her huge magical power for a moment. The fact that she is a grumpy, shut-in artist is what really makes her famous. She paints all day in her room and gets really mad when people bother her. It is so much fun to watch a real dragon goddess act like a total NEET hikikomori. You will want to tease her right away.
Dusk's character design is a work of art in every way. Her hair is a beautiful dark green color with teal highlights that go perfectly with her huge tail and dragon horns. Her clothes are a great mix of traditional Yanese robes and modern streetwear. She literally brings a huge calligraphy brush with her to the battlefield that she can use as a sword. She fits the perfect grumpy tsundere mold. She acts like she hates you and always complains about having to leave her room. But she still paints beautiful landscapes for you. Fans are completely obsessed with her because she has a lot of godly power and a lot of antisocial waifu energy at the same time. She will put your enemies in an ink painting just to get some sleep.
Dusk is the best wallpaper for your screen because it looks so beautiful. Artists love to draw her in traditional Chinese ink wash styles that match her powers. There is a lot of beautiful fanart of her painting glowing dragons or just angrily hiding under her blankets. If you want a desktop background that perfectly combines classy traditional art with the energy of a shut-in, you need to have this grumpy dragon waifu on your screen.
