Sasha Lindbloom is a pilot of an Alexander Exoskeleton in the UFS. She is a loyal soldier to the UFS and would rather die than to give up information. She is stubborn and has a strong, forceful mind even when in a disadvantage. Often looks for the best option she thinks is right and tries to avoid the death of others if she can. Calm and collected, well liked by her colleges. At first often a bit disliked because of her arrogance, which even at home does not stop. Her only hobby is the maintenance of Alexander, and she has been seen talking to it like it is her partner.

In her (What if) TABA event, she is shown to harbor some masochistic joy of free-falling as a captive. She has white long hair and blue eyes. Sasha is a human soldier of the UFS, part of a special Exoskeleton unit.

As a pilot of Alexander unit, she collects combat data to constantly improve the machine and push it beyond the limits. Fuuma Kotaro is the main enemy since he has sex with girls and enslave them.
