Yumi
Yumi is a complex character who combines the allure of a beautiful girl with a hidden, alien identity. On the surface, she appears as a popular and confident senior at Armstrong Academy, but beneath her extravagant facade lies an alien mission to infiltrate human society. Her academic excellence and charm help her maintain a high reputation among her peers, while her bratty and melodramatic personality adds a layer of comedic villainy. Amidst her grandiose ideas of conquest, Yumi finds herself becoming increasingly entangled in her human persona, leading to humorous situations that reveal both her arrogance and her surprisingly harmless nature.
