Scarlet just kept shooting, she clearly had something she wanted to try in front of everyone and in the middle of battle she couldn't quite get it yet.
Her normal arrows were clearly not strong enough to pose much of a threat to the giant in front of her.
Every arrow she shot at Gunther was seamlessly blocked, there were arrows all over the platform and she was being chased around. Gunther was clearly getting frustrated, he was used to battlefields or fighting with Sins, things that wouldn't run away from you but to you instead.
He thought this was going to be easy pickings but shamefully forgot how those who were smaller than him were often very agile making it harder for people like him who were brutes.
Gunther wanted to make a good impression on not just the Kingdom but the King as well who sat watching their fight so closely. He'd never been anything special back in Wilderden, he had hoped to change that in Arkadia.
