Ep 17. Ah! the Chair of Demonkind Descends!

Keiichi and Belldandy are going to an electronics shop because Keiichi has to get some parts for his motorcycle. The shop is very busy and Keiichi starts to feel frustrated. He notices that the customers are fixated on a particular chair. The craze spreads to him too. Everyone who sits on the chair feels a spark of pleasure passing through their body. When Keiichi sits on the chair, he is transported to a different dimension, where he meets a demon who tells him that she is the queen of the underworld and is seeking a new king to reign alongside her. Keiichi, who is attracted by the power of the underworld, accepts her offer. As he returns to the real world, he realizes that the chair is cursed and everyone who sits on it will be lured into the underworld. He decides to destroy the chair along with the demon that tempted him. With the help of his friends, he manages to destroy the chair and break the curse. The demonqueen is defeated and the underworld is safe once again. Keiichi learns that true power lies within oneself and that one should not be enticed by external temptations.
