Jherwin Kabayo's extreme jealousy, envy and ego

Jherwin Kabayo still expressed his absolute frustration over Supreme Leader Nanobana obtaining a new power core named Epsilon and her expanded capacity of playing Genshin Impact. It is known to Supreme Leader Nanobana Kinako that she wanted to play Genshin ever since discovering the game few years ago but she was unable to due to Gamma being incapable of handling such game. Supreme Leader Nanobana Kinako accessing this game allowed her to play her dream game. This is what angers Jherwin as he desire only sadness in the leader's life and failure to do so disappoints Edgar. It is known that Jherwin has an absolute obsession to please Edgar and aims to get his expectations by being extremely loyal to the demon.
