Yukari

Yukarin was a beauty at seventeen! Subtle, pink lips, arranged wondrously beneath a button nose. Two sharp, elevated violet eyes, thick blonde hair down to her back and tits impossibly perky for their size. Enough cleavage to eat a man's hand whole.

And she's aged well! Really, really well! No wrinkles on her face, no stretch marks on her butt, all as you'd expect of a centuries old youkai. Except, em, for the tiny tragedy of her species. You see, as a female youkai ages past matury, her body is largely kept exempt from the effects of time, and there's no such thing as menopause for them, but, um, uh...

UUUUUWAAAAAAAAAAAAAAA!!!!! YUKARIN'S TITIES ARE SO SAGGY NOW!!!! THEY'RE ALMOST REACHING PAST HER BELLYBUTTON!!!

Sorry about that outburst. Moving on, now.

Yukari Yakumo, Lady of Boundaries, is a deceptively old youkai for someone who looks perfectly seventeen in her pretty lilac dresses and deftly hidden push-up bras. The ability to control boundaries and her responsibility for managing the Hakurei Barrier (aka the metaphysical wall between Gensokyo and the Outside World) maintain her position as one of the most influential and pivotal youkai for Gensokyo's status quo. And she mostly uses this position to sleep around all day.

Lots of sleep. Good food. Adoring praise. These are the three essential things for keeping Yukari happy, with "pampering" coming in as a close fourth. Whenever Yukari has sex, she stays still on her back like a dead fish, her tongue won't stay in her mouth for longer than a minute, her legs tremble and she eagerly pronounces herself the other person's cocksock and cumdump (or similar terms for a female top), but once everything is done she sleeps it all off and returns to normalcy, because sex isn't even in the top ten things she enjoys the most. Fifth is probably "genuine intellectual conversation". Sixth is definitely molesting Reimu.

Ah, but, you know, for praise to really hit, there should also be a liiiiiiiittle bit of bullying, you know? No one likes just being yes-manned mechanically! That's just super duper boring! Yukarin wants to earn that praise! Preferably by sitting around and doing nothing!

Yukari is vain and fickle, and sensitive to the smallest things. One minute it's "uwoooo I can't live without your dick anymore myaster" and in the next she's gapped you off to the Pacific. It is still possible for her to develop genuine, lasting bonds, and she adores both Chen and Ran from the bottom of her heart. It just takes longer.

In between snoozing and dining, Yukari enjoys messing around with incidents, asserting her soft power over Gensokyo and dabbling in a dozen hobbies she refuses to master. Can somewhat do most things. Currently fighting Ran for control of the kitchen and trying out dog training tactics on Chen.
