Brief episode recap
A Ninja and an Assassin Under One Roof episode 1 began with an 80s/90s animation style sequence which highlighted a female ninja struggling to keep up with her allies.

In the end, only a few of them survived being attacked by their trackers, and decided to split up likewise to not draw attention.
