hit through a wall V15,C4,P3

As she spoke, she grabbed a nearby bench and threw it.
But...
An unidentifiable explosion appeared with Kakine at its center.
The bench was blown to pieces and even Kinuhata was blown away.
Her small body flew through the air ten meters before landing. She broke through the
thin wall and into some room.
