Yui x Oka

Just found myself a new Yandere Sim OTP, all thanks to Say hello to Yui x Oka... a ship involving a sweet-n-shy occult worshipper and a sickeningly pure evil student. Ahhh....what a perfect combo~!

Headcanon time: Yui was the result of an unholy union between a normal human man and a female yokai (aka: demon), who was in the guise of a human when she slept with said man then dumped baby Yui in his care afterwords. For as long as she could remember, Yui always carried an evil aura around her... being filled with the greatest delight whenever she sensed suffering or pain around her. Though she mostly resembles a regular human girl, her eyes are the biggest indicator of her demonic lineage... being sharp and slit-pupiled when she's in a particularly wicked mood. One of her favorite past-times is tormenting students like the Delinquents, who all turn very cowardly when in Yui's presence. 

On one particular day, she caught the Delinquents tormenting poor Oka (who was on her way to an Occult club meeting)...calling her weird names and pushing her around. Deciding to have some fun, Yui scared off the Delinquents and turned her attention to Oka. Rather than being chased away or weirded out by her....rather, Oka was so in awe as if she'd seen an angel. Turns out, Oka's got a little "fetish" for demons... and seeing the half-demon lineage in Yui's eyes made Oka's little heart go "doki-doki"~

Intrigued by Oka's reaction, Yui decides to start dating her. Helping her with her rituals and keeping her safe from all the recent murders happening around campus. And though she knows it's "sinful" to be spending so much time with a demon (even if they're only "half"), Oka is just SO enamored with her darkness and refuses to leave her side no matter what~
