In the basement (part 1)

"Say, Mace, is that door booby-trapped?"

Cranberry asked while carefully examining the old, unassuming door supposedly leading to the basement.

"I... I don't think so...? I think it's only locked, my fathe... big sister, what are you...?!"

Mason tilted his head trying to remember if ever saw or heard something about that, but then he witnessed Cranberry raising her weapon and activate the skill that caused it to start glowing.

Her question was just a formality, even if the brown-haired young man would swear on his life that there was nothing wrong with the door, she wouldn't believe him anyway.

*SMASH*

...and she simply busted open the door while using the counter skill...

"Big sister! What are you doing?!"

Mason gasped in shock.

Cranberry just glanced at him and shrugged her shoulders.

"Now there will be trouble whether we go in there or not. So let's just go."

She smirked and pulled on Mason's wrist.
