For that one anon who was curious about the "Nazuna Lookalike", by the way, her name is Izutsu, and she's actually a special kind of Kitsune familiar called the Izuna, which are heavily associated with (or depending on who you talk to, are the same thing as) the Kuda-Kitsune and Osaki-Gitsune, with the names varying depending on the region.

Her primary (and quite literally only) ability is the power to summon additional Izuna Familiars, up to two at a time. They cannot attack, and can't take much damage, but they will take hits for the ally that they're currently placed with, and their primary power is the ability to buff the stats of all teammates within their range by a flat 50. The buffs of the two tokens stack with each other, and additionally, Izutsu also buffs the stats of other Monster Girls within her range by virtue of being a Shaman as well. Meaning she can provide a surprisingly huge boost to everybody around her. Her skill does nothing but expand her range and give her more Izuna Familiars to summon should she start to run out, but it's all she really needs from it anyways.
However, she can only be obtained during a Yokai Banner, which run for limited amounts of time, and are infrequent. If you want her you'll probably have to wait a while before a chance to get her shows up again.
They do look a lot like each other though.
