Series: I saw a Maricha expedition so I observed it (fool)

An expedition squad of three pet Marichas wanted to test their newfound excalibur. Strays have no rights so they decide to try to kill an adult stray Marisa, but she fought back and killed two of them. Their daddy pet Marisa came to save them but because of his own overconfidence the last one got killed anyways.
