Aliens Among Immortals Episode 8

After a massive massacre of Upper Rank Demons, the Ubuyashiki clan is now determined to take down Muzan and his Shitani army. To counter this enemy, they have set up a training camp for soldiers, run by their top elite members, the Hashira, to train them into perfect soldiers. Amidst all this, Tanjirou is still recovering from his injuries from the previous attack. On one hand, his sister Nezuko is being researched, while on the other hand, Tanjirou, without wasting any time, sets out to train with every Hashira because he has sworn to destroy Muzan with his own hands.
