Holo office stage clear (RTA, no upgrades) in

Roughly re-checked the timer to 22:37.80 by myself in media player since I knew I got that time wrong with my little fingers racing to reach the numpad from my bed. Turned out to be very slightly wrong.
I had a lot of fun trying to figure out how to do this since it seemed no-one else was really interested. Hakos Baelz (my goat) wasn't really the play since she lacked any form of survivability, so she was a no-go. I tried with Ceres Fauna next and got way better results, but didn't wanna do more runs with her. Eventually I landed on Takanashi Kiara, as her skills provided both survivability, and crowd control. That's all I really needed for this to work.
