Datta

Self-deprecating and chaotic: he makes fun of himself and his content, admitting that one month he uploads a lot and the next almost nothing because "his cerebellum works better that way".
Close and affectionate with the community: he asks for drawings, memes, letters and even "sacrifices/offerings", responds to fans and says things like "I love you all".
Dark but not forcedly edgy: it deals with extreme phobias, real mental disorders, traumatic childhood shows, human experimentation, disturbing video game easter eggs, end-of-the-world scenarios, etc. The narration is usually calm yet intense, and many people find it evokes a feeling of "pleasant unease."

A Spanish-language content creator (Latin American style) who makes long, detailed icebergs about dark, disturbing, and psychological topics. He's not a mainstream YouTuber with millions of subscribers, but the algorithm pushes him quite a bit because his content generates viewer retention (30-45 minute videos about strange things/fears).

Hair: Long, straight, pastel pink, with straight bangs and strands that fall to the sides.
Accessory: Black headband with a large black bow/bow on top of the head.
Face: Completely black (total silhouette, no visible facial features except the eyes).
Eyes: Large, round, white with bright black pupils. They give off a slightly empty/creepy-cute vibe.
Clothing: Black top with a Peter Pan-style round neck (white/light grey line).

It has no lips, but it can open its mouth which is full of fangs and a long, sharp tongue.

feminine body, looks like a woman but it's not really known what it is.

The face is completely black (silhouette/void)
It represents emptiness, the unknown, what lies hidden beneath the surface, the dark mind, or inner fears. It's very typical of channels that discuss disturbing, psychological, or "iceberg" topics (just like Datta does). The featureless face gives a sense of anonymity and suggests that "something more" is hidden behind it.
Pink hair + black bow + big white eyes
It's the "cute" part. The pink and the bow give off kawaii/innocent vibes, while the huge, fixed eyes create unease. This contrast (adorable on the outside + unsettling on the inside) is the core of the menhera or yami-kawaii aesthetic (cute + dark/mental illness/creepy).
