double tackle

Before Tsuchimikado could adjust his aim, she straightened out and tackled him square
in the gut. Receiving a blow that felt like it would have been able to destroy a door or
even a thin wall, Tsuchimikado’s body flew a few meters back.
A tremendous sound rang out and he had trouble breathing.
“Those movements...Is that Anti-Skill’s arresting technique...?”
“This is my own arrangement. If Anti-Skill used this, the children would die.”

Tsuchimikado fired his gun as they spoke, but Teshio easily dodged his shots just by
moving her upper body. She kicked towards him aiming for the moment his clip
emptied and the gun was torn from his grip.
Another tackle followed.
With a dull crushing noise, Tsuchimikado became pinned between Teshio’s shoulders
and the wall. She quietly moved away from him and his limp body slid to the ground.
