Series: The Life of Maricha who Desires a Harem (aminosan)
Maricha is a popular yukkuri who has every beautiful yukkuri in the clan as part of her harem. But one day a betrayal happens, one of her harem members, the beautiful Marisa-oneechan, got married to the dull Myon. Maricha already hated Myon because everyone calls her the clan's best hunter (a title clearly meant for Maricha) but laying her hands to one of Maricha's harem members was the last straw. Maricha finally decided to punish Myon with death.
Of course all of that are just shithead delusions. Maricha is just a perverted brat that nobody likes but everybody tolerated since she hasn't actually done anything bad yet. And this attempted murder on Myon was the perfect reason for the clan to finally dispose of her, by giving her a taste of her own medicine.
