S01E01 Invincible Poster Girl / Another Poster Girl
Miki, Megumi, Makiko, and Akihiko are introduced. Miki demonstrates her willingness to slack off from work in order to help others. Miki and Megumi face off.
Miki drinks beer and gets drunk. In her drunk personality, she is very cute, shy and husband looking girl. In the other episode, Megumi is also drunk, and becomes an abusive and violent tomboy. But after while, they (literally) knock the alcohol out of each other, and are back to their normal (but still violent) selves again.
Miki works at her mother's ramen restaurant. She appears normal, but she can become violent when provoked causing issues in their otherwise peaceful lives.
