Lucas Hiddlestone.
What was he known for at first?
A pervert, a man with no morals at all.
A villain, someone who was supposed to hinder Elijah.
Someone filled with pride...no someone who is still filled with pride and used that as fuel to grow stronger.
It was unknown what caused his change to become a somewhat better person.
Was it the fact that he never met the Sword Saint previously?
This time, he did.
The sword saint was more active than this time, and as a result of this, he met Lucas, making him his student after seeing his tenacity.
Or could it be someone else that was the cause for his change?
Yes, there was.
Alan Peccator.
He was the cause of the change, even if he was unaware of it.
In the previous iterations, There was only Elijah in Shield, and the gap between Elijah and Lucas was not as large as the gap between Alan and Lucas.
The prodigy that reached rank C at 16, who would believe that crap?
