Omg sorry I thought you meant Mahiro!!! I thought you said brother!! And yes it's weird cause Oni is a middle aged man and the glasses girl is literally a newly young adult. I suggest you don't ship them cause it's weird, disgusting, disturbing, and you will be considered as a creep. Be careful of who you ship, dear!!
He is not middle aged!!! lol He is a 3rd year high school student who repeated a year. If he reapeted the year 2 times, he is 20 years old at maximum. And she is a 2nd year student so 16-17 years old. Not that big of a gap. That reminds me I had 2 male classmates when I was in the 1st year of high school. One looked like a 20 something years old and the other looked older because he liked to keep on a beard. They were both about 2 m tall 15 years old
That i'm now shipping oni-sama and the glasses girl?
