I associate Laina with being a sweet person, Crying Freeman with Crying Freeman and a passion for 90's anime, Jorge with Gorgeous George, Shiroi with cross-stitch and FFXV (including the photography component; snapping that beauty beside Iga), The Bloody Aperture with a well groomed spokesperson/ TV/ Radio personality, Claimh Solais as a character who wields a massive sword, Tattered Seraph with being shrouded in mystery, Uzo with Hazama, Rugal with Vega (Claw, not Dictator), Nagumo as a collector of ancient artefacts (articles, texts, interviews etc) and last but not least theplottwist with the Master Librarian... Don't even try to argue with plottwist... Don't.
Sorry if I've missed anyone.
That's about it. Some of these associations may seem simplistic or not to some peoples' likings, which is fair enough because I'm not sure how well I know anyone in this forum tbh. I also believe I'm probably not a very easy person to get to know, which is why I chose the name/ association of Zangetsu.
