A Loyal Family Dies for Their Country, Swearing to Avenge Their Blood Feud

I trained in martial arts from childhood, but my master was too violent, so he sealed my abilities. Five years have passed, and my martial arts are about to be unsealed. But my family has been slaughtered, I’ve been framed and accused of treason. Once my powers are unsealed, I will make them pay for this blood feud. Do you really think I’m useless? Then I’ll show you that this “useless” man is someone you can’t afford to provoke.
