Cosmo Samurai
In episode 1, Tsuruhime and the Cosmo Samurai rescued the heavily damaged TOM from deep space after his escape pod exploded. After meeting TOM and realizing they share a common enemy, she asks him to join the Cosmo Samurai in their quest to defeat the Akutou. In episode 3 Tsuruhime showcases her master swordsmanship by cutting down swaths of robots aboard the Akutou mothership. When the Cosmo Samurai reach the command center of the mothership she attempts to cut down the Akutou Mid Boss but can't cut through his barrier. After Hakase hacks into the ship and shuts down the barrier of the Mid Boss, Tsuruhime faces him in one-on-one combat. She easily kills the Mid Boss and believes she has finally gotten revenge for her father by defeating the Boss of the Akutou. However, the actual Boss of the Akutou reveals himself and mocks the Cosmo Samurai, revealing the Mid Boss was merely a pawn in his organization. TOM then makes a declaration that they’re coming for him next.
