Granted, you become a Tsuchinoko. Basically, you're similar to a naga, except pretty short and with a fat butt-tail. You can slither around just fine, but you can also move around by putting your tail in your mouth and rolling. You can also jump, even in mid-air with some effort. No, seriously, the rolling and jumping parts are actual Japanese mythology.
Since you're also a monstergirl, you have the standard increased sexual stamina. You're also very stretchy - a necessity, due to your diminutive size. You're pretty good at charming people and especially lying - which is good for enticing possible partners. Finally, due to your status as a cryptid, you possess supernatural luck that, while not exaggerated, will still help you in most things. Like earning money, finding people to fuck, finding a tailor willing to make you custom-made clothes, stuff like that.
There is one aspect your luck doesn't work, though: avoiding capture. You see, since you're a lucky criptid, a lot of people are willing to capture you to benefit from your luck. So you'll be kidnapped, often. Your luck will prevent bad scenarios, but not annoyances. So, for example, expect to be mummified in ribbons and gifted to a rich woman's daughter as a one-night escort.>I wish to be part of this harem of giga-diapered girls.
