Mr. Nietzsche in the Convenience Store (also known as Nietzsche-sensei) is an autobiographical Work Com written by Matsukoma and illustrated by Hashimoto. The manga has been serialized in Monthly Comic Gene since 2013, eventually getting reprint runs in the online magazine Comic Bridge.
Based on Matsukoma's Twitter chronicles about working a late-night convenience store, the story follows a fictionalized version of Matsukoma as he trains the sardonic new hire Tomoharu Nii, a blunt, philosophical man from his university's Buddhist department given the nickname "Nietzsche-sensei" for his attitude. Joining them on the night shift are Hisashi Watari, a co-worker and senior of Matsukoma who is obsessed with lottery tickets and money, and the convenience store's unnamed, eccentric manager, along with a rotating cast of juniors to play off of.
The manga was later adapted into a live-action drama that aired in January 2016, with Shotaro Mamiya as Nii and Kenji Urai as Matsukoma. Others casted are Jiro as Watari, Jiro Sato as the manager and former SKE48 member Matsui Rena as Matsukoma's childhood friend Kaede Shioyama.
Mr. Nietzsche in the Convenience Store provides examples of:
- Brutal Honesty: Nii's habit of speaking his mind gets him in trouble as much as it makes the targets of his commentary think about their own opinions.
- Dark and Troubled Past: Before working at the convenience store, Ken did a number of shady jobs under fake identities. This turns out to be because he's rich, rather than due to hard-knock living.
- Deadpan Snarker: Nii's stoic attitude extends to his commentary, occasionally making it hard to tell if it's a snide comment or his usual honesty.
- Fictional Counterpart: 777 (pronounced 3-Seven) stands in for the 7-Eleven Matsukoma worked at.
- Hilarious Outtakes: The drama has a few videos, with most of the jokes coming from the cast trying not to laugh at Jiro Sato's improvisations.
- Hollywood Atheist: While Nii himself is a Buddhist, some of his outbursts are done in this manner. His Establishing Character Moment is bluntly telling a customer "God is Dead" when an Unsatisfiable Customer tries to invoke the "customers are gods" stock phrase, and compares the Mainstream Obscurity of not having read a popular manga to not having read The Bible.
- Idol Singer: Moe is revealed to be a member of an underground idol group. This was foreshadowed and lampshaded in Episode 8 of the drama, when Kaede notes how much like an idol Moe sounds when she relates not being allowed to date.
- Improv: The manager's scenes in the drama are noticeably more unscripted than the rest of the cast's.
- Love at First Sight: Kaede for Nii, and, oh boy, does she fall hard!
- Money Fetish: Watari is obsessed with winning the lottery, and is hyper-sensitive to the dropping of loose change.
- Only Sane Man: Matsukoma is arguably the one with the most common sense among all the characters.
- Secretly Wealthy: Ken. Actually, it's not-so-secret.
- Stalker with a Crush: Kaede towards Nii, with an additional dose of Abhorrent Admirer.
