Slice-of-Life

Summoned to a place called the “Tower of Struggle,” I was introducing myself to ‘players’ I had never met before and discussing the ‘system’ when―
    “…What’s that about the Smash option?”
    “Smash? Hold on a sec. Let me check it again.”
    I realized that my status window was different from the others.
    “It says I can hit the opponent hard and deal 150% physical damage.”
    [Smash] [F]
    [Hits the opponent hard, dealing 『1,521%』 physical damage.]
    “And what about First Aid?”
    “…It says you can wrap a bandage to restore 50 HP. But how much is 50, exactly?”
    [First Aid] [F]
    [Wraps a bandage to restore 『503』 HP.]
    Why is only my skill description strange?
    Is it a bug?
