Anon meets a family of three yukkuris who rudely demand sweets from him, but he starts kicking them around. Just as he's stepping down on the Marisa for trying to kill him, th Reimu points out that Marisa apologized, so he has to forgive Marisa.
After a bit more confirmation of that issue, he takes his foot of Marisa, and immediately the family demands reparations in the form of sweets. Instead, he kicks them one after another, apologizing for doing so, and pointing out that they should forgive him. Finally, he stomps down on Reimu's lower jaw and steps hard on the Komaria, and apologizes for both.
When Marisa objects, he points out that it was the one who said 'Apologizing means being forgiven'; just like how he forgave it for trying to kill him, he should be forgiven for stomping on the Komarisa.
"Okay, Komarisa. Sorry for stomping on you~"
With that, he ends Komarisa's life.
In a rage, Marisa yells that it won't forgive Anon. He confirms 'no matter what?', and when it replies in the affirmative, he tells it he won't forgive it for trying to kill him, which is why he is taking revenge by crushing Reimu next. Marisa screams that it has already apologized, so that sin should have been forgiven.
"If you say you should be forgiven after saying sorry, then you'll forgive me even if I kill this Reimu, right? If you say you won't forgive me, then likewise I won't forgive you and kill this one in exchange."
Marisa sobs as it tries to think of a way around his words, but when he removes his foot from Reimu, it immediately starts gloating and demanding sweets again. It also tells Reimu to go back to their home quick, only to realize that Anon took his foot off not because he stopped crushing it, but because there was no more need to crush it any further.
Its mourning is interrupted as Anon begins to step on it, and Marisa begs for mercy and forgiveness. He says he will, and that's why it should also forgive him for killing it too. Marisa protests that that's not fair.
"Who says? You're the one who said that at the start. Give up and die."
"Nooo... Help... heeeelp..."
"I refuse. See ya, Marisa, sorry for crushing you~"
Afterwards, Anon disposes of the crushed bodies in the yukkuri bin.
