Well, wolf tengu affords you similar abilities as Momiji at outset, though they're several levels lower than hers at first.
For example, her Long Sight power comes in at Rank A(Goes from novice, to F, then E, and all the way to A, and then through 9 to 1, like mabinogi).
Whereas the player-owned one would start at Rank D.
While being a flower youkai would afford you somewhat similar abilities as Yuuka's only much weaker, and lacking the spark skill.
For example, Yuuka's life-based skill, Farming/Gardening, comes in at the maximum rank, R1.
The player-owned version would be quite a bit weaker, due to being a relatively newborn youkai, only around Rank E at best, to signify their newness.
There will be more details depending on what youkai type is chosen.
