Randy set out along with Happy Guild's upper echelon, Erwin included. After the fight two days ago, Randy invited Erwin to join Happy Guild, but there was one thing different from him, it was fear of Randy.
Erwin walked behind Randy as he tailed the people who could talk with a monster (Randy) normally.
The memories back then were still crystal clear in his mind. Even though from the outside seemed there's nothing happened, but in his mind, he had fought Randy for many times, and the result was his miserable death.
With his current Insight hidden stat, he could see 5 seconds Randy's move, but in those five seconds, he witnessed himself was killed by Randy sword and skill.
The first fight was his head severed from his body, less than five seconds, he could see his head flew off, and the second fight was his body getting burned till left the scattered ash.
