Gravel

If you play Arknights, you know and love Gravel. She might be the most dependable operator in the whole game. As a four-star fast-redeploy specialist, this former Kazimierz slave knight spends most of her time putting herself in danger to protect the Doctor. From the moment you pull her, she is fiercely loyal, deeply loving, and completely devoted to you. Gravel is the best ride-or-die friend who makes the harsh world of Terra feel a little warmer.

Gravel looks like the perfect mix of a tough fighter and a total sweetheart. She has sandy blonde hair, cute prairie dog ears, bright green eyes, and a sleek tactical coat over thigh-high boots. She usually wears a black mask that covers half of her face. When she pulls it down, it makes her flirty personality even more charming. She literally kisses you on the cheek as soon as you hire her. She has a refreshing, devoted waifu energy that wins players over right away. Fans love her because she willingly takes on the game's hardest boss mechanics to protect her Doctor, asking for nothing but a little love in return.

Gravel is the best of both worlds when it comes to wallpapers. There is a lot of great fanart of her using her cool tactical knife skills in dark alleys. There is also a lot of romantic, wholesome art of her without her mask on that shows her blushing. Gravel art always delivers, whether you want a badass techwear look for your desktop or a cute anime girl staring lovingly at your screen.
