Fumiko has bushido X, where X is the number of attacking creatures. (Whenever this creature blocks or becomes blocked, it gets +X/+X until end of turn.)
Creatures your opponents control attack each combat if able.
X is variable. The bushido bonus is calculated each time Fumiko's bushido trigger resolves, based on the number of attackers at that time.
