In Episode 11 of Nurarihyon no Mago: Sennen Makyou, Kubinashi has a flashback of the Second Heir, with his then young child, Rikuo. What is the name of the song that was playing in the background? I have been trying to find it but can't! The time interval from which the song plays is from 16:11-17:30. My apologies for not making that clear.
