Synopsis:

This week's episode picks up where last week's left off with a broken down Basura who has just saved Mio. Yuki tries to face off against the Masked Demon but he's gone before she can do anything effective.

Back at home Maria informs Mio that Basara is recovering nicely. Meanwhile Mio is plagued with thoughts about her choice to stay on earth. Basara recalls his training in the Hero village and the day that the legendary demon sword was released and most of his village was slaughtered. Even then, Basara protected people. He managed to use "special" powers to destroy the demon.

Maria and Basara discover that Mio has left the house. Mio has gone off to meet the Masked Demon. She tries to fight him but nothing works. Just as Mio is about to go to the Demon realm with the Masked Man, she's saved by Yuki. She breaks the barrier that protects the Masked Demon. She vows revenge for Basara. Basara finally arrives to the fight and uses a special power to stop the attacks of the Masked Demon.

Basara manages to take down the Masked Demon (with a bit of help from Maria). But is then suddenly attacked by another demon. Mio screams and her power knocks everyone out. Her power threatens to destroy everything around them but Basara is able to use his special power to stop her overflow.

Basara and Mio return to school. Basara meets his friend Yahiro Takigawa on the roof and figures out that he is the masked Demon that attacked them. Basara however has come to negotiate instead of fight. He reasons they should continue how they were instead of coming out fighting all the time. Yahiro reveals that the Demon Lord after Mio's power is Zolgia.

Meanwhile, Basara's Dad seems to know something about Basara that may soon come to light.
