Ironic that in isekai at peace, Alice is the one who plays the role of the clown teasing people.
Normally this could turn into a fun match where both sides pull stunts on each other, but SBA means this can't be a causal thing, so Alice would probably just be amused by Bugs toon force, and try to analyze it, obviously this sort of ability doesn't exist in story, so i think regardless of how ridiculous and safe it seems, she would perceive it as a threat.
Normal things 6 Kings use as a byproduct of their attacks include negating defenses, causality manipulation which makes their attack always hit, and opponents attack miss, and even stuff like negating causality manipulation.
Also thinking about it, Alice's fighting style doesn't really translate to other verses, its a little more broken than I thought, in verse she has the best stealth, which is a combo of information manipulation, perception manipulation, and invisibility. Even among people on her level, when she uses it, Alice could literally be around them and they wouldn't know until she attacks, people below that have no way of detecting it, so her fighting style is to be a stealthy assassin really, and if the opponent is above her go UBF, which is reactive evolution making her stronger, faster, and hax resistance.
