Chipp's 41236K~D is a Force Break. Do 41236K and then quickly hit Dust, it changes from his command grab to a horizontal slashing attack. You need 25% tension to do it.
Roman Cancel is when you press three attack buttons (except Dust) after a move connects. It costs 50% tension and immediately returns you to neutral. There's a red circular effect and the announcer will say "Romantic."
Force Roman Cancel works the same as a regular RC, but it's done during very specific windows of certain attacks. Enabling Input View in Training will let you see these windows as a white flash in the input bar, which fades to blue. These cost only 25% Tension.
Faultless Defense is a special sort of blocking that negates chip damage and pushes you farther away, but puts you in extra blockstun. You can do it by holding back and pressing any two attack buttons (except Dust, and not S+H). The thing with 66 > 4PK is FD Brake, it instantly stops your dash momentum. If you just stop dashing normally, you have to go through a stopping animation - this lets you skip that. So basically dash forward, then tap back and two buttons to FD. You can use this to run up and throw someone quickly, or block an attack while dashing.
As for boss I-No's attack (Megalomania, btw), all you need to do is avoid the boxes until she stops. If you try to hit her or pass over her, she'll attack automatically. So just stay the hell out of the way. There are three patterns iirc - two you can just duck under (though one will require you to move as it shifts outward) and one you have to stand near her and double-jump over.
Boss Order-Sol... I don't even know. No continues, a certain amount of Overdrives, other stuff?
Here's a thread.
If you need a handy reference for any of this stuff in the future,
don't forget the wiki.
