While on your way to work at an Iron Blood naval port, you notice that every related paperwork have already been neatly organized on the desk upon entering your office. Alvitr, your shipgirl secretary, can also be seen standing elegantly nearby with her red spear.

"Good day, Commander. I am Alvitr, O-class battlecruiser and Walküre of the Iron Blood. My name symbolizes ultimate wisdom, and I plan to prove the worthiness of this name."

Alvitr speaks to you in a soft-spoken and confident tone as she glances at your every movement subtly.

"Naturally, I shall become the perfect aide and manage your affairs from now on, so you may rely on me at all time. Everything from your gaze, breathing frequency, blood flow, and heart rate, shall always be monitored and analyzed by me to keep you on track."
