These matchups are the ones you absolutely dominate in, the opponent will have a hard time dealing with your character's tools and trying to counter them but that doesn't mean you should let your guard down. Any good player can still beat you up good even if they are playing a character you mostly win against.
6-4
These matchups are the ones that you solidly beat thanks to your kit, but they can still compete with Adachi's toolset with stuff of their own, even if they are at a disadvantage. If you can play well then you should be fine fighting these characters.
5.5-4.5
These matchups could be even, but the characters listed here can struggle against Adachi's kit even by a small smidge, leaving them at a slight disadvantage.
5-5
These matchups are even for both the Adachi and the opponent you're facing against. What more can I really say.
4.5-5.5
The matchups listed here aren't quite exactly in your favor, as the characters listed here may have tools that you have but are just straight up better. The reason why they aren't 6-4 however is because your tools can still mess the opponent up by a good bit.
(Shadow Type Labrys goes here btw the tierlist didn't include her lmao)
4-6
The matchups listed here aren't the greatest for Adachi, and can sometimes be straight up infuriating to fight against if you're facing against certain characters.
These matchups, while winnable, can be a uphill battle for the Adachi player. The characters listed in this tier generally have a much more easier time fighting Adachi. While it can be frustrating, it is not unwinnable, keep a cool head and be patient.
3-7
Consist of characters that invalidate Adachi's best buttons and his persona, or have way more mobility that it can be hard for the Adachi to react punishing against.
Mystery?

Adachi
"Beat him down! Bad guys need to be punished right?"
Mirror matchup, not much to say here besides look out for your own bullshit and know how your own character works. See how your opponent plays and know how to abuse your own weaknesses to beat your other self.
