Finished. Only two unidentified characters remain (between Anshinzawa and Hosoe, and behind Neo Universe) someone already did when I was writing this comment, thank you!, then it could be annotated.

Spent almost two hours tagging on phone (20.45 -> 22.25 GMT+7) and I'm proud with the result. (And 500+ tags too!)

Edit:
Thank you Iyagushka for annotating them all!

That Machan looking at us is so perfectly detailed.
