Shuel

Shuel was an arrogant and selfish girl, who didn't really care for Ari and her friends. She was focused on her mission to collect Hopeless Energy. Shuel did whatever it took to collect hopeless energy, even if it meant sabotaging Ari and her friend's activities or endangering the lives of others.

However, by the end of season 1, her character grows. Shuel genuinely learns to care for the Flowering Girls and forms a real friendship with them, and are now working together to solve problems and collect Hopeful Energy.
