These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Bludgeoning Angel Dokuro-chan
Audience-Alienating Premise: Bear with us here: an angel comes back in time to repeatedly and brutally murder (and promptly reanimate) a junior high student, in order to stop him from creating a 'pedophile's world' where all females don't age past 12 years old. And it's a COMEDY!
Ear Worm: Pipiru piru piru pipiru pi! Not only is this repeated in the theme song, it is chanted in a high, squeaky voice every time Dokuro is required to resurrect Sakura, who dies more than Kenny ever did.
