Time passed quickly between Klaus' intensive training to regain his optimal state and strengthen himself and the big news that constantly plagued the city.
It's been a week since the fight with that shadow-like beast, and nothing different or serious has happened. Klaus has been getting deeper into understanding energy and his power. Also, now that he can train during the night, his level has increased considerably.
The problem is that he can't use the full power of the Cursed Field, which is annoying. He tested it several times and realized that, in mortal combat, he couldn't rely too much on it during the night, but it was still amazing for unexpected hits or bold moves.
