Gesui yo! Hanamura-san

is a Japanese manga series written and illustrated by Kibako Kiyu. The manga was serialized on ComicWalker and published in Japan by ASCII Media Works under the Dengeki Comics NEXT imprint from December 2013.

Synopsis
Hanamura Asahi is just starting out in high school, where she hopes to meet her special someone! However, Hanamura is a major jerk, who is someone who always seems to get out of things without damaging her reputation. For instance, on the way to her first day of school, she collided with an old lady, who then needed help getting home. Knowing it would make her late for her special first day, she just pretended she'd never seen the old woman. She also does things like ignoring small children being bullied, and maneuvering around on public transportation to get her friend (instead of her) next to a groper. Hanamura is excited about her high school life, and she's not going to let stuff like 'caring about other people' get in her way!
