Once, when he and Bella were off shopping, someone crashed into Bella, making her fall and cry in pain; that was the first day when Richard's parents received a warning from the police since Richard ended up smashing a whole set of beer bottles onto the asshole's head.
Those close to them shall always remain safe by his side, is the principle which he follows. And if someone tries to hurt them...then Richard himself doesn't know what he might end up doing in rage.
Currently, the person whom he promised to protect all his life was getting attacked by several white-robe-wearing worms.
The only thought that came to his mind when Richard saw Lilia in such a state was to shred them into pieces while keeping their consciousness intact so they could feel the pain of that degree which no human should experience.
And Richard was well-set on making it true.
