The (dead) teen from the alleyway

"Have you heard the rumors?"
"No! What rumors?!"
"Shhh! Keep your voice down, he could hear us"
"Sorry, but who do you mean with he?"
"Haven't you heard the rumors?"
"No, and again, what rumors?"
"There are rumors spreading about certain apparition"
"Like a ghost?"
"Yeah, the ghost of a kid that stands alone in certain alleyway, that he will appear to you and give you three wishes if you say 'Hanagaki san Hanagaki san, are you there?' But in exchange he will take something from you"
"Wow, really?"
"Yeah, they say he is the ghost of a misfortune teen who got sold his soul to a demon in that alleyway long ago, in 1955, and now he is confined to grant wished to whoever calls his name two times and then offer him Taiyaki"
"Should we try calling him?"
"No! He said if we make the wrong wish or make him angry he is going to curse the person for the rest of eternity in the mirror dimension"
"Ack! So scary~!"
