Thank you, I appreciate the update. I hope I don't intrude but I'd like a few clarifying clauses for first-time readers, such as "if a unit's size goes lower than its Minimum, it is destroyed", clarity if an asterisk only shows up for minimum Size, and something about Size 0 being 1 for calculating Damage/Resilience. That is so non-zero Offense/Defense values mean something for a Size 0 characters, yet Size X pacifist group with Off/Def of 0 would have 0 Dmg/Resilience. Although I say this because I'm not as familiar with it as you are, there may be no need for units with 0 in relevant stats.
I don't know how old your Black Lagoon splatbook is but I keep coming back to it. I think it's the one anime IP I am most familiar with. I also check the Doom splat to see how the statblocks hold up.
