Fumikage and Mina are rather minor characters in the series, but with still enough screen-time to allow fans to create a decent opinion- and even grow fond of them. Mina and Fumikage seem to get along relatively well, and Mina, like all the girls, has a fondness for the “cuteness” of Dark Shadow.
The two have never truly interacted all too much due to the absolute differences between them, but still carried one notable interaction early on in the series; a fight in the U.A Sports Festival. The fight didn’t last for too long, and ended with Fumikage as the victor. Mina didn’t take this personally, rather stating that it was fun.
Outside of the main series, Fumikage and Mina share a somewhat decent interaction in the second MHA/BNHA movie, “Heroes Rising”. During the attack by the villain Nine, they fight alongside one another against Nine’s sidekicks. Mina soon finds herself prey to one of them, a man named Scythe. He almost manages to kill her, but Fumikage freaked out and leapt from his own fight to push her from harm’s way. Afterwards, he sees her off as she’s lifted- and carried of on a stretcher. Mina weakly smiles, and gives him a thumbs up, and pats Dark Shadow’s head.
TokoMina is quite a rare-pair in the MHA/BNHA fandom considering their lack of interactions. Regardless, like all rare-pairs big and small, it has still managed to gather a following, and even some fanworks of its own. It is, of course, rivaled by more popular, mainstream ships for the characters, such as TokoTsuyu and TokoShoji for Fumikage, or KiriMina and MinaOcha for Mina.
The most popular thing to notice about them is the striking differences in their personalities; Mina is a loud, giggly socialite, while Fumikage is a dark, rather brooding young man. These differences lead to a potentially interesting dynamic, and easily hold a great appeal to lovers of the “Opposites Attract” trope.
The rather opposing color schemes the two hold are enjoyed by TokoMina fans as well. Mina’s bright, alien pink against Fumikages’s midnight black make for some interesting- and aesthetically pleasing fanart!
