Nura: Rise of the Yokai Clan

Rikuo is the grandson of Nurarihyon thus becoming the third heir of the Nura clan, but he has not started acting like the third heir. All the yokai want him to be the Third Heir, but he just wants to be a normal human.

An old ally of the Nura Clan visits to have a discussion about Rikuo's role as future head of the demon clan. Zen has been a long-time supporter of the Nura Clan, a play-mate with Rikuo when he was little; with a weak constitution their family has lent the Nura clan their support in return for protection. Rikuo once again evades the question, explaining he does not wish to become their leader, and Zen leaves doubting the future of the Nura household.

A new student Yura, joins Rikuo's class. She knows a lot about youkai and can sense their presence. Rikuo's friends decide to form a paranormal investigation group and decide to have the inaugural ceremony at Rikuo's house since they've heard rumors of it being haunted. Much comedy ensues while they explore his house against his wishes. It comes out when they are attacked by a rat that Yura is an onmyouji (exorcist). While Kanna and Yura are heading home they are attacked by a group of youkai.
