Pacing is horrible. Development is forced as hell. And Grenade has 1m radius blast?
I'm no expert, but aren't grenades made to spew shrapnel, not explosive force? Even if a person's on the far side of the room, they'd still probably be badly hurt.
You're thinking of fragmentation grenades. I'm thinking this is something more like a concussion grenade meant to kill/immobilize using explosive force alone in a small radius. It's possible for the explosion to propel debris within the room to cause damage, but I've heard if you're low on the ground, it's possible for the debris to not hit you. Someone try this out and report back.
Considering the situation these girls are in, we could even chalk it up to the grenades being slightly modified. I'm no expert though.
