Red Leaf High Needs You Once Again!

So it's supposed to be 2 runs per day and still give good exp? I failed to notice. How do I get past that room with all the 4 friends in it (and a bunch of ninjas to kill)? It keeps telling me to talk to the teacher but she's nowhere in the room.

she hides behind the friends sometime. just use npc chat to find her

i think first char you log on gets the two runs
