Cosmo Samurai
In episode 1, Yasuke 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, TOM joins the Cosmo Samurai in their quest to defeat the Akutou. In episode 3, Yasuke showcases his fighting skills with a spear and minigun by destroying large amounts of robots aboard the Akutou mothership. In episode 4, After Awaji is hit by the Mid Boss' eye drone, Yasuke deals the final blow to the drone with his spear. He is shown to be visibly upset at the thought of Awaji dying, even crying hysterically and shouting his name in despair. However, when this body is revealed to be a clone, Yasuke hugs Awaji and continues to cry with joy. At this point 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.
