ngl whoever told you that either does not know what trans mean or doesnt know what futanari means or just lied. 99% of the cast here is futanari, a 3rd gender in this series' universe, they are born with fem presenting bodies, use she/her pronouns and both male and female genitalia and reproductive systems.
The cast are all very comfortable with their bodies and femininity and genitals and have zero interest in any transitioning and zero interest in men.
The only character that would probably be considered trans rep in the slightest would be Tansho, but even then its not trans rep because she has a micro peen and gets treated terribly in the series bc of that and just desperately wants her penis to be bigger and wears a cup thingy to make it look like its actually sizeable instead.
havn't read this but came from a comment saying this has trans representation?...
