Get the Clock-kunmug. a creature featuring in a japanese short series. named after the first phrasse he heard on tv - yes it's true - "domo kunichiwa"(pardon the spelling!), Domo is a large brown furry creature with a twitchy attitude at best. his huge gaping maw provides many comedy moments througout the series, but the eyes - they're dead - like a doll's eyes... ^ ^

Get the trash~kunmug. A speeding truck who is a major character in most isekai anime/manga. It appears at the very beginning and hits the main protagonist dead, causing him or her to be reincarnated in another world as a slime or whatever.
Alice: So let me get this straight... "Truck-kun" appears at the start of every isekai... runs over the main protagonist... and causes them to be reincarnated in another world?
Bob: Bingo.
Bob: Bingo.
