Chapter 0

Prologue

I was summoned to a place called the "Tower of Struggle." While introducing myself to the other players I had just met and discussing the "system"—

“…What does the Smash option say?”

“Smash? Wait a moment. Let me check again.”

“It says that it deals 150% physical damage when hitting the target with all my might.”

[Smash][F]
[Deals ‘1,521%’ physical damage when hitting the target with all my might.]

[Emergency Treatment][F]
[Wrap a bandage to recover ‘503’ health.]
