Episode 74 - The red Tetsusaiga that breaks the barrier
The villagers cannot stand against the powerful bats, and Inuyasha is powerless due to the shield that Shiori is generating against her will. Tsukyumaru, Shiori's father and Taigokumaru's son was a peaceful demon and loved the village and never wanted to see it harmed, and so Shiori's mother does not understand why Taigokumaru wishes to see it destoryed along with everyone living there. Taigokumaru tells them that because his son fell in love with a human he no longer wished to carryout his job of protecting the barrier, and so he had to kill him. Now Shiori will do the job her father refused. Taigokumaru fires a blast at Inuyasha who reverses it into the Bakuryuha, but Shiori's barrier prevents it from doing any harm. After hearing that her grandfather killed her father, Shiori's rage forces Taigokumaru outside of the protective barrier. Inuyasha sees his chance and kills the giant bat. Now Shiori and her mother are reunited and the village is saved. Inuyasha refuses to kill the little girl mearly to power up Tetsusaiga, but Shiori offers his the red orb she carried to generate the shield. It's power should be the same as if Inuyasha had bathed Tetsusaiga in her blood as he had planned. Suddenly Taigokumaru's spirit emerges from the ball and tries to kill Shiori and her mother, but the spirit of Tsukyumaru protects them both from harm. Sure enough the orb powers up Tetsusaiga making it's blade glow red, and now it is powerful enough to break almost any barrier.
