[Crossover] The Shut-In Can't Lift Anything Heavier Than a Paintbrush!

Tsujido Hisashi's life is full of sporty guys.

His childhood friend plays basketball,

his high school classmate plays volleyball,

his neighbor plays tennis,

his pen pal swims,

and even the son of the owner of the hot spring inn where he stays on vacation is a world-class figure skater!

But he's a good-for-nothing who nearly dies after running just one kilometer!

The only thing that comforts Tsujido Hisashi is that his cousin is just like him, a shut-in couch potato.

But!!

His cousin has lost his mind and decided to run in the Hakone Ekiden!

"I bet he'll give up halfway!"

"If he really runs in the Hakone Ekiden, then I'll... I'll... exercise for an hour every day!"

"No one can make me leave the art room and go to the sports field!"

Tsujido Hisashi clings to a pillar and refuses to let go.

"Quit it. You said you'd do it," someone says, knocking him out and dragging him away. PS:

A crossover with sports anime, with other series that fit the setting making appearances too!
