Some skills, not all, I haven't tried the others besides the mentioned are not using Mado Gear Fuel even if it requires it to cast.
Skill descriptions all saying it would require/consume Mado Gear Fuel.
Note: I don't have any Mado Gear Fuel on my Inventory and also no Kick Step Card set.
Skill Demonstration (Sorry I don't know how to create a video :c ) :
Note: It would have been best to see when it's a video. I'm sorry idk how :c
Note 2: They are not in the same order because I forgot to take a picture of where I was standing.
(Chronological order by time: Front-slide -> Acceleration -> Backslide )
Last Note: Not all are affected by this, I tried using Arms Cannon and it consumes Mado Gear, but I'm not sure on the other skills.
