>>34327402. Tsugu has a twin/doppelganger/split personality.
Hatoba Tsugu isn't the only person to feature in her videos, there's also Kijio Tsugu.
https://twitter.com/KijioTsugu This twitter has all the videos that Kijio has been in as well as another video you might not have seen.
If you watch that first video listed in
>>3432740there again you'll see in the background that there are two identical hats hung up, and if you pay attention to the tooth brushing scenes again, you'll notice that the towel is in a different position for each one, and a hair pin disappears. The picture that was used the first time Hatoba was introduced on twitter shows one girl in focus with another one stood behind her, blurry, separated by a red line at their feet (this red line comes up again later). Pic related.
(
https://twitter.com/__LM7__ This is the account of the person who designed Tsugu and I'm pretty sure is in charge of the whole thing, as well as voicing Tsugu herself.)
There are some similarities, they look more or less the same, they each have a mole under their left eye.
There are some differences, Kijio wears her hair in a ponytail and smokes. Her voice is a little deeper. In her introduction video she seems to be in an office or something with shuttered/barred windows, and in another (the vtuber parody one) she's in a well-lit room, unlike Hatoba who always seems to be somewhere dark. When she introduces herself the sound glitches when she says "Tsugu". The article points out that she seems more adult and also kinda boyish, and so might actually be a he, or it might be Hatoba pretending to be a boy, or it could be nothing.
