this weird promotional song for instant curry showed up in my youtube recommendations and i clicked it because the thumbnail had rin and nadeshiko. and now i want instant curry. didn't even know they made that. good job nisshin
looking at their website though they don't have a promotion with dungeon meshi which seems like an oversight? all you have to do is get the narrator to go "karee meshi.... karee meshi." and you're done, seems like a shoe-in to me
