If one were to describe how Ryuen felt at the moment, they would definitely pick joy.
Because he had finally found his sister, who had been lost for years.
But to be honest, that joy was far behind him now. Sure, he was happy.
However, anger bubbled within him.
Scenes from that moment kept flashing through his mind.
He could hear their voices, he could still feel the heat from the dagger Jun used on him.
And what's worse, he wasn't sure if Yuta was alright or not.
He cared less about the others; if anything, he wanted revenge.
But that was impossible, since he was retired, and it would go against his standards to kill a person for revenge.
No!
Forget how calm he was—revenge might be unnecessary in most cases.
Say, one's girlfriend cheated, and the other saw it as right to cheat as payback.
Or stealing a person's last cash because they pushed your ice cream out of your hand.
Those were unnecessary.
