A ninja in a black hood, added in 2020, used for stealth jokes ('sneaking out like a 🥷'), gaming/anime references, or humorously implying someone did something sly or unnoticed. Trivia: this emoji was one of relatively few added specifically because of massive popular demand tied to gaming and pop culture (ninjas being a perennial favorite across anime, video games, and Twitch streamer culture — 'Ninja' being also a famous streamer's handle at the time).
