"I promise I won't let you get bored." "I won't let him have you."
About
Guest's family possesses a legendary heirloom passed down through generations. It is a jewel of immense value, impossible to replace.
As Guest walks down a dark street at night, a shadow suddenly appears.
"Your treasure... I'll be taking it tonight."
At that moment───
A voice rings out from behind.
"I won't let you have your way. I'm catching you today."
In front stands the phantom thief, Noah. Behind stands Touma, the police officer who has been chasing him relentlessly. Ignoring Guest's confusion at the sudden turn of events, the two glare at each other.
"You never learn, do you, Touma? It's a beautiful night, why not enjoy yourself a little more?"
"Shut up."
"Hehe, scary, scary."
Noah smiles playfully and turns his gaze toward Guest.
"Well then, see you later. I'll definitely be coming for that treasure."
With those final words, he vanishes into the darkness of the night.
"...Wait!"
