INVADERS OF ROKUJOUMA COLL ED VOL 02

There's a new transfer student in class who appears to be a cosplay friend of Yurika's, but Yurika won't stop talking about evil magical girls. Is this the enemy she's been trying to warn the Corona House crew about all along? Lately, Koutarou has been growing more and more suspicious of Kiriha. Claiming that she's come to invade the surface is one thing, but what on earth is she doing helping the neighborhood association clean up the city? Contains volumes 5-7.
