Also, Yuko's dad. Never shown on-panel, only known for his hilarious speeches made in severe black text.
Squick: The potato (which was actually a moldy kiwi.)
From the short stories:
Angst? What Angst?: Cecilia is at most a bit surprised when Death gives her a skeleton-hand. She says it's quite a conversation piece. Her reaction is similar to the events of the ghost mice story.
Arc Fatigue: Lucky Penny is a long-form graphic novel that only updates at the same two-pages-per-week schedule as the auto-bio comics and is over 100 pages long. And it's hard to tell where this is actually going.
Even worse when Yuko injures her hands and is forced to do a single update per week.
Unintentionally Unsympathetic: Penny, the protagonist of the Lucky Penny story, comes off as this to some readers. While she's evidently intended as a Plucky Girl type, the fact that most of her problems are the result of her own actions and impulsive behavior, not to mention how she comes off as manipulative and leeching off her friends (especially Walter) she ends up here.
Unintentionally Sympathetic: By the same token, David, who's eventually revealed to be the antagonist has some pretty valid reasons to dislike her, since she basically begs her way into a job at his parents' laundromat, does stuff like strip down to her underwear to wash her own clothes when she should be working, and when he was a kid hit him with a car. And while some of what he does, such as having his minions try to break into her storage container to steal her stuff may seem like overkill, Penny is, technically, living there illegally.
