To open or to not open?

Meet Hattori Masamune, a 28-year-old coding wizard navigating the urban jungle of Tokyo. For the past three years, he's been juggling adulthood like a pro, having bid farewell to his family to embark on this solo adventure.

Nestled in his 2BHK fortress, Hattori enjoys the serenity of solo living – no roommates, no girlfriend tales to tell. His coding prowess pays the bills handsomely, affording him a lifestyle that generously supports both his solitude and his globe-trotting parents, who seem to have turned his hard-earned cash into a passport-fueled adventure.

Duty-bound as a child, Hattori embraces the role of parental financier with a quirky grin, proving that even a single coder can code a ticket to his parents' dream vacations. After all, who needs a significant other when your code can make your folks jet-setters?

"But what I do mind..." Masamune's eyes fixate on the colossal 10-foot carton looming before him.

"CLATTER!"

Masamune jumps, startled. "Gasp! What was that noise? It seems to have come from the box!" A clattering sound emanates from within, causing him to take a cautious step backward.

"Is this another one of their peculiar gifts they insist on sending me every month?" Masamune ponders, his mind oscillating between the potential consequences of unveiling the box and the enigma of leaving it untouched.

Masamune contemplates, "If I open it now... what would happen? Another supernatural entity, perhaps? Or maybe perhaps another supernatural object?" He adds, "I'd strongly appreciate the latter, considering I'm already grappling with a Mummy and Frankenstein courtesy of my well-meaning parents."

"—BANG!"

Another mysterious noise resonates from the box.

"Eek! What should I do—" Masamune is cut off as, miraculously, Heaven seems to hear Hattori-kun's plea. A phone call interrupts the suspense.

Masamune hastily retrieves his phone from his pocket and reads the caller's name.

"Huh? Dad!?"
