Saika

Saika is Souka's subordinate. She forms part of the Shadow Squad, and mostly gathers information. She used to live in the Lizardmen marshes but moved to Tempest by Abiru's order.

Lizardman
As a nameless Lizardman Tribe member, she was an olive anthropomorphic lizard with violet hair, equipped with light armor.

Dragonewt
After being named by Rimuru and evolving into a Dragonewt, she took a more human appearance and wears ninja-like attire. She's also able to hide her wings and horns, which retained the color she had and makes her perfect for infiltration missions as she is able to pass off as human.

Background
Originally a Lizardman working under the orders of Souka.

Story
She first appeared following Souka to Tempest after receiving orders from Abiru to sharpen her abilities. After being named by Rimuru, she began to work under Souei's orders. She has been seen fighting with Souka and the rest against Charybdis attack. During Falmuth's invasion she was asked by Rimuru to gather intelligence within the barrier, without fighting. She then took part in Tempest's counterattack. She was sent to the north as part of Souei's team and managed to kill the soldiers without much effort.
