In mission 1 they do know who Mirko is, even Ochaco says "wow, she is rabbit hero mirko, she number 5 in the billboard,...!". Izuku explanation is simply a "character introduction thing" to the readers and to use the gag that every time Izuku meets a new hero, he goes "full hero fan" mode and tells a lot info about the hero.

Mission 2 (december 3) come out after the fight against Star Villain (September 30)
