Decided to do some quick draft work of Otomi's transformations this morning, since sleep has eluded me.
The forms seen here are Base, SSj, and SSj2 respectively, with the second photo showing the Flow* alternates.
*Flow is a Kaioken-esque powerup that Otomi can stack on top of her base form as well as transformations. Whereas Kaio-Ken achieves added strength by multiplying the ki within the user's body -- to potentially destructive effect -- Flow operates by improving the efficiency of ki flow, able to crank more power out of the same amount of ki.
The best way to visualize this, is that the more a form drains on one's stamina, the greater the returns of using Flow alongside it will be. This makes it invaluable for use with Super Saiyan 3, however Otomi opted to train SSj3's power into her Super Saiyan 2 as it seemed to be a more potent and efficient setup to work with.
Flow can theoretically be bolstered by the principles of the Kaio-Ken, however the versions seen here are strictly Flow combined with the base or Super Saiyan states respectively.
