K2 / ケイトゥ (Love City / アイ・シティ)

The adaptation of the Ai City (Love City) manga was originally planned as an OVA but was eventually released as a film. There are strong parallels between the aesthetics of this move and the Cyberpunk 2077 video game. It's a wild ride of a movie with a nice soundtrack and some wild concepts.

K2 initially loses her memory after losing in a Headmeters battle with protagonist Kei (K) and I won't spoil past that. One of the cooler effects in the movie is the digital numbers that show up of the Headmeters' foreheads. I would have like to replicate that but unfortunately generations giving actual digital numbers are rare in this model. Is there a better way to train those forehead numbers?
