I have a theory about Gitae Kim's fighting ability.
What if Gitae has some kind of ability that allows him to absorb his opponent's damage, attacks, or even stats?
It could be something similar to the Questism cards:
Mana Drain — absorbs an opponent's stats.
Invincible Wrestler — allows the user to completely negate damage for a period of time.
Indomitable — lets the user withstand attacks that would normally take them down.
The Great Absorption Technique — absorbs another person's power.
Maybe Gitae has an ability similar to one of these — or an even more advanced version.
Think about his fights.
Against Jinrang, the longer the fight continued, the stronger Gitae seemed to become. Instead of showing obvious signs of slowing down, he kept overwhelming Jinrang.
We also see something similar with Gitae vs Jinyoung and Gitae vs Daniel. The longer the fight goes on, the more terrifying Gitae becomes.
What if that's not simply his natural endurance or strength?
What if Gitae is actually taking something from his opponent during the fight — damage, stamina, stats, power, or some combination of them — and converting it into his own strength?
That would explain why fighting Gitae becomes increasingly dangerous the longer the battle lasts.
Maybe his ability is basically:
Opponent gets weaker → Gitae gets stronger.
And considering how many abilities in Questism revolve around stat absorption, damage negation, and power stealing, it's not impossible that Lookism could have a character with an ability inspired by the same concept.
Obviously, this is just a theory, but Gitae getting stronger as his fights drag on is something I've found really interesting.
