CSA0487: Reimu: Go 4-on-1, win anyway.
Shenanigans in a Magical Forest
Your attempt was an overwhelming success.
「FANTASY HEAVEN」 is a LAST WORD SPELL CARD, above and beyond all other types; they are fuelled by one's own LIFE FORCE, and usually require a phenomenal amount of power and concentration just to keep oneself from passing out after they finish. This one enables you to float in the air away from REALITY ITSELF, and is therefore also a TIMEOUT CARD, in which the user is invulnerable to DANMAKU from their opponents, who must simply weather it out (under the SPELL CARD RULES, all DANMAKU PATTERNS must run on a TIMER, and when it runs out, the pattern ends as if you had been hit; this enables battle to progress even if both sides are particularly good at dodging).
This variation is five times as powerful, ten times as dense, and doesn't have a TIMER, because you're allowed to do that sort of thing when they've broken the SPELL CARD RULES.
