E: fandom hates wikitext lol
This is in the realm of pure speculation: and so a discussion post rather an editing of Gin's page itself.
The theme of Gin's catharsis skills seem to be a mystery, other than being english spelled out using katakana. Sasara's skills are based off old idioms, Kiriko's are in japanese and seem to be phrases that would be in a samurai movie.
So what's my theory of Gin's skills? Gin is known to be a fan of western superheroes. If you try and connect his skills to that of current super heroes, you can see some connections that don't seem like that much of a stretch:
! Skill !! Superhero
|-
| Avenger's pain || The avengers
|-
| quicksilver || There is a superhero called quicksilver, but he did not have a recent movie appearance and assume it's based on the more popular hero, the silver surfer
|-
| iron piercer || ironman
|-
| venom bolt || venom
|-
| hawk shot || hawkeye
|-
| marvelous combo || captain marvel
|-
| blood pool || deadpool
|-
| spider bolt || spiderman
|-
| panther rush || black panther
|-
| vision bolt || vision
Note how all of these are all from Marvel, and also had recent movie appearances. The more astute of readers may notice that I have left out two skills: Tall Spark and Dhampir Rave.
Tall Spark's original name is トールスパク, rom. tooru supaku. Although we pronounce it a slightly different way, "tooru" is another way of pronouncing the name of the norse god, Thor. (proof: https://ja.wikipedia.org/wiki/%E3%83%88%E3%83%BC%E3%83%AB?oldid=42635344) Thor happens to also be a superhero in a marvel movie, so this seems highly plausible. This means that the proper translation for this skill is Thor Spark. I do not blame the translators for missing this reference since it was also difficult for me to understand his skill naming scheme.
Dhampir rave, being the ultimate skill for Gin, is in spoiler territory. I warned you.
Dhampir Rave does not have a specific character named after it. There is one Marvel character, Blade, who is a Dhampir but is not called that. It's less of an obvious connection than the other skills, so i looked deeper.
The Dhampir is noted to be a half-human, half-vampire creature, having the skills and abilities of both halves. ref: https://en.wikipedia.org/wiki/Dhampir
When compared to the rest of the skills, which are all superheroes. Gin's ultimate skill is one named after someone who is half superhuman and yet not. This matches his character development in his deep dives. His obsession with superheroes is a stand representation of what he thinks manliness is supposed to be, what with the obsession with protecting other people and all. After coming to terms of who he is, he's not even a superhero at this point. He realizes he does not want to be a superhero, or only a man to realize his self identity. Both masculine and feminine aspects, superhuman and human, are a part of who he is and what makes him himself.
I wrote this down since I don't think anybody has written in depth about this, but I thought it added such an interesting depth to an already interesting character.
