Shizu

The three adventurers who Rimuru previously encountered in the cave, Kabal, Elen, and Gido, are sent to investigate the forest. Overhearing their plans, Shizu joins them. In the forest, they are pursued by a swarm of giant ants; Shizu demonstrates her skill by defeating most of them, and Rimuru rescues her from the final ant.

Shizu is also from Japan: she was summoned when she was young, during the bombing of Tokyo.
