Name: Asahi Suzuki
Role: School Spirit Committee President
Personality: Little Miss Sunshine
Asahi is the president of the school spirit committee. She is also the sun that brightens everyone's day, she will go to all lengths to cheer every one up. Asahi like helping others with nothing in return, her radiant smiles will shine over and dark clouds. She would also give everyone a buttercup flower (that she grew from the Gardening club) and say "Don't cry, my little buttercup. Today is a beautiful day!"
One day she had notice that Senpai was not as happy that he could be, so she try's her best to make him smile. But when he did, her heart nearly stop. She had never felt this kind of happiness before, and she wants to see more of it. So everyday she would look for Senpai and make him smile, and the more he smiles for her the more she fall for. And who knows, maybe Senpai would fall for her as well.
Asahi is a mix, her father is Japaneses and her mother is Eastern European. She is also always surrounded by people, so killing her isn't an option. You may want to find another way to eliminate her, like perhaps secrets of her broken family, or messing with her insecurity and getting rid of that annoying smile of hers.
While drawing her I was looking at the designs of the current rivals (mostly Hanako Yamada) while thinking about personality of Pinkie Pie (from "My Little Pony") and Madeline Hatter (from "Ever After High). I was also thinking about Little Miss Sunshine (from "Mr. Men).
