Sumida Saiko

She belongs to a different battalion than the protagonist.
Although she pilots a precision-type unit, she does not carry a shield.
Instead, she wields a massive hammer, favouring a reckless, assault-oriented combat style.

A true battle maniac, she feels pure joy in the act of fighting.
She only recognizes value in strength. If she deems someone to be weak, even if they are a superior officer, she will bare her fangs without hesitation.
She harbours a twisted sense of admiration for the protagonist, whose strength borders on the heroic.

“That presence… yes. Very good. Excellent.”
