I'm actually really glad you asked that. Bravery is necessary to make it feel more like an anime. Bravery is supposed to be the spiky haired protagonist,  the one that has no notable skills, but is still gonna try their best, and through the power of determination/faith in the cards/manliness of their own soul/humanities uncrushable spirit, they WILL win the tournament/save the world/graduate/be the very best that every was!!
Where as the other characters are all more skilled, but also specialized and don't always get along without their token leader.
