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.
Arc Fatigue: For Episodes 8,9, and 10,the Psycho Lesbian antics of Shiraumi(who doesn't contribute to the plot in any real manner, not even by fighting) and the twins Kyo & Kyo Sawagi, who decide to fart around with getting Sen's attention due to the long haired twin's crush on her.
Crazy Awesome: The Kyo sisters fight with shopping baskets and it's used as a weapon
The plot in general, treating shopping like a Shōnen battle
Cult Classic: By no means as mainstream as most anime, it has great animation and a great concept of Shonenizing an everyday occurrence like shopping in a grocery store
