Feeding yourself isn't easy on a fixed budget in boarding school. Yo Sato learns it's even harder when brawls break out every night at local supermarkets the moment bento meals go on sale. The only way to get a bento is to fight the wolves for one.

Yo and Hana join the Half-Pricers Club. Its leader, Sen, teaches them the ropes, then sends them out into the wild to fend for themselves. There's a lot to learn, but it looks like Yo might turn out to be a successful wolf after all.

The kendo club at school has their own ideas about how to acquire half-price bentos, and its captain makes a tempting offer to entice Yo into their fold. The time has come for Yo to ask himself what his motivation is for being a wolf.

It's nothing but trouble when Yo's half-Italian cousin Ayame shows up and starts causing problems. Meanwhile, some shadowy organization appears to be gathering information about the local wolves.

Yo inadvertently finds himself caught up in a brewing turf war between wolves from the east and west sides of town. Wolves generally do their own thing, but this time they might need to work together to defend what belongs to them.

The Monarch, leader of the eastern wolves, claims he wants to take over the supermarkets in the west as well. Sen comes up with a plan to foil him, while Ayame learns there might be more going on here than meets the eye.

The Half-Pricers Club gets free tickets to a Hawaii-themed water park, so it's excursion time! While there, Yo learns that supermarkets aren't the only places where bento brawls occur.

An unfortunate mishap lands Yo in the hospital. Twin sisters Kyo and Kyo, student council officers from Ayame's school, are trying to learn more about Sen. When they mistake Yo, covered in bandages, for Sen, a comedy of errors ensues.

Homemade bentos are the order of the day, but sometimes these can prove just as dangerous as bentos won in battle. Asebi believes Yo is a big fan of her cooking, while Ume decides to take things up a notch with Hana.

There's a new wolf duo in town, and they go by the name Orthros. This pair seems to be as unbeatable as they are mysterious, but the real surprise comes when it's revealed that their true identities aren't so shrouded in mystery after all.

A certain supermarket puts fresh eel bentos on sale one day each summer, and this is sure to attract plenty of wolves. But to make it there, first Sen will have to recover from a cold, and Orthros will have to overcome the specter of their painful past.

The old nemesis of Orthros shows up in town to undermine them once again. With Sen still sick with a cold, it will be up to Yo to figure out a way to rebalance the playing field for all the wolves, as they vie for seasonal eel bentos.
