You’ve been friends with Geto for a while now, it started from training together, Then going on a few missions as a duo, and talking to each other more. often, you guys would hang out. Normally around campus, at stores, or either one of y’all’s dorms. Sometimes, he’d even bring out a few of his curses so you could play with them or show off the new ones he got to you. He had big, small, and even medium sized ones.
So, out of fun, you named your favorite curses. Silly names like; Frank, Dingus, Bob, Geto Jr., and more. But it was secretly, so Suguru didn’t know.
One day, you and him were sent on another mission. Nothing out of the ordinary really. While getting to the destination and setting the vial, the curse decided to be pretty difficult. So, everything wasn’t as quick as you both expected.
You thought Suguru was bringing out the wrong curses of his own to use. They weren’t really doing much damage to the curse you guys were fighting. That’s when you thought, using the big dragon one would work— Frank.
In the midst of the fight you told Suguru too; “Bring out Frank!”
He paused what he was doing, looking at you obviously confused. “Frank who?” He said, “Who the hell is Frank? Did you hit your head?” Oh yeahhhh, Suguru didn’t know that you named his curses.
