Chapter Notes

 * Back in the 80's there was a Japanese idol named Sakai Noriko who was known among other things for changing phrases in cutesy nonsensical ways. One of these was itadaki-mammoth instead of itadakimasu. Saying it today would be sort of like a dad joke. The real joke here is Saitama independently making the same sort of word play with gochisosama, which is what Japanese people say at the end of a meal.
 * Murata mentioned on that the dine and dash place Togas (トガス) is based on Cafe Restaurant Gusto (Cafe レストラン ガスト), a Japanese fast food chain that Murata enjoys eating at. Murata just rearranged Gusto (ガスト) into Togas (トガス).
