Ruli and the gang are researching the paranormal sightings around the city when they stop to investigate a rumor about a haunted karaoke box. It’s said that if a certain song is sung, a mysterious and creepy voice begins to sing along with you.
I'm glad I didn't have to undo
the seal on my hand.
يسرّني أنّني لم أضطرّ لإلغاء الختم عن يدي
Ich bin froh, dass ich das Siegel
an meiner Hand nicht lösen musste.
Me alegro de no haber tenido
que liberar mi sello.
Me alegro de no haber tenido
que liberar mi sello.
Et je n’ai même pas eu
à défaire mon sceau…
Sono contento di non aver dovuto sciogliere
il sigillo sulla mia mano.
Que bom que eu não tive que desfazer 
o selo da minha mão direita.
Я рад, что не пришлось
снимать печать с руки.
