So I decided to start doing some practice doodles.
If you're not familiar with the story between these two characters, the tall one Galatea (Gallie) only existed in a sort of virtual world up until she turned 18. The other girl Mei, intruded into that world 5 years before the start of the story (when she was 13, and Gallie was 11). Gallie saves her from a monster (Mei thinks she's a boy), and her dad (an Alien) takes Mei to his school in America (TEXAS).
There unbeknownst to her, Mei is attacked is attacked daily by monsters on this virtual realm she can't see or interact with. She's saved by Gallie who has developed into what she thinks Mei would think a strong woman would look like. Essentially a Bancho/Yanki. Mei, spends the next 5 years trying to hack servers trying to find her "Prince", and right before she's to graduate, she finally succeeds. Gallie saves her from the same monster from 5 years ago, and Mei's latent techno-empathy tunes her brain to the server bandwidth, allowing her to see the virtual overlay world that Gallie lives in even without the headset.
She's kept at the school for the next 2 years until Gallie's 18th birthday when she is able to get her real body that has been developing all this time.
