Mika is still technically older than Yuu. He would turn 19 before Yuu would turn 19. Mika was used to being in the position of  the eldest even to the other orphans. He was not able to see Yuu grow to be independent during those 4 years. So it would make sense for him to be overly protective of him still even when Yuu can hold his own weight. I mean yeah he has relied on his demon alot but he is still a skillful swordsman and he's still alive.
