[Western Crossover] Your Sister Just Escaped Heaven to Beat You Up

“Ah, yes, this is Miss Metis.” The old butler sighed at the family portrait on the wall, its colors beginning to fade. “She used to be Lord Wayne's sister, and she lived in this house for a very long time...” “That was a long time ago... But I still remember the delighted expressions on Mr. and Mrs. Wayne's faces when she gave her first cry. They kissed Miss Metis on the nose and stroked her soft cheeks.” “Three years after Miss Metis came to this house, Lord Wayne arrived too. Of course, back then he was Master Wayne. But that doesn't mean Miss Metis lost her parents' love. On the contrary, the couple spoiled her even more to keep her happy.” “Fortunately, Miss Metis never let all that pampering go to her head. She remained polite, quiet, and elegant... Look, here's a photo of the siblings together on Lord Wayne's seventh birthday.” Damian, standing beside the old butler, hesitated. “Wait. Are you sure this is my father and Miss Metis?” “Of course.” The old butler dabbed the tears from the corner of his eyes with a handkerchief. “Though Miss Metis was already in very poor health by then. She could only lie on the sofa while she posed with Lord Wayne...” Damian looked at the Border Collie lying on the sofa with an expression of absolute superiority, and the young version of his father sitting beside it, grinning so hard his eyes had disappeared. He fell silent. I, Metis Wayne, was once the beloved daughter of a human couple. As a purebred Border Collie, I understand why the couple had a hairless baby. But if you were going to have one, why on earth make this terrifying little thing my younger brother?! “Bruce,” my mom said, holding the drooling little creature and setting him on my belly. “This is Metis, your big sister.” I'm not his sister! Take him away! Aaaaaah, he's drooling all over my freshly washed fur! Mom, take him away! Get him away from me! Unfortunately, no matter how much I struggled, Bruce grew up tugging on my tail. Along the way, he was kicked flying by me countless times, got a blast of my breath in his face, and had his food stolen by me. In the end, I still gave in to those blue eyes he shared with my mom and grudgingly accepted the noisy little brother. Even so, my place in this family was unquestionable. So, years later, when I walked into Wayne Manor again and saw my little brother leading another dog into the house, every hair on my body stood on end. “Met...” My utterly clueless little brother didn't notice my fury. His eyes welled with tears. “Metis?” In the dead silence, I charged at him, sprang up with all my strength, dodged my brother's hug, and planted a paw right in his face! Alfred told me everything! The device around my neck started playing a recording automatically: So you were the one who threw away my special dishes and dining table, you brat?! [Please note] 1. The Border Collie is just a Border Collie. She will never turn into a human. 2. A short story about family affection. It probably won't be very long. 3. Quite a lot of dog content. 4. A crying Lord Wayne may make an appearance. Theme: Teaching humans to love
