Honestly, the more I read about how the different styles are described here, the more my DnD comparisons come up.
Akakiru and Midorikatai are strong in battle, hence I see both as the Fighter class and Barbarian class respectively. They're REALLY good at combat and surviving said combat, but otherwise are not heavily focused outside of it. Sure, they can allot some time and effort in branching out, but only on a few specific niches outside of battle.
Aoyu is obviously the Cleric or other half-casters, they're powerful because they're competent both in and out of combat. Which kinda reflects half-casters in general in DnD, overpowered-ness through versatility is the name of the game for them.
Kiihakai is obviously every caster class represented. Outside of combat is their main focus, and in combat, the "spells" you use are basically just to enhance what you can already do, or to manipulate the battlefield, or to just blast things by using the style to enhance your chi blasts ala Dragon Ball. Not to mention what you could do with Alchemy, which they focus on alongside Handseals (because I refuse to believe only Kurokonton is the style that masters them).
And now Kuro, which obviously fits the whole Rogue and maybe Bard archetype to a tee. They're all about skills and whatever shenanigans they can do to bypass what's in front of them. Not to mention, this style is almost exclusive with speed (their whole gravity and entropy shtick), thievery (as a damn concept since they can somehow copy techniques and even memories), and basically just being unfair, which, again is kinda like the whole point with rogues and bards as a concept.
It is a known bug if you open menu at a certain page during that event your score gets lowered for now don't open the menu during that time.
Ahh, I see. Thank you, guess I'll just open the page later after the trial.
