I'm the Tragic Little Sister, but My Life Isn't Tragic at All

Yujin had always known that the person his junior high classmate, Maika Kibutsuji, cared about most was her older brother. Even her catchphrase was, "I hope everyone can love him." It wasn't until he heard that she and her brother were not related by blood at all that he understood her attachment to the label of "siblings" came entirely from Maika wanting to become "family" with him. Yujin: "Did you know? There's actually a way to become family without being related by blood." A few years later, Maika, who now had a "big family": "Yay!" - Born in the Heian era, Kanazuki Maika was originally named Maika Kibutsuji, and her older brother was Kanazuki Muzan. But one day, after growing up with the name of a "god," her brother suddenly turned into a "demon" and even split himself in two. One half went off to cause trouble, while the other became an idiot. Looking at the abandoned half of her brother, who had lost his sanity and most of his intelligence, Maika decisively stuffed him into a box, then set off on a journey to find her brother while carrying him on her back. - During the Sengoku era, Maika met a swordsman whose older brother had also become a demon. So she earnestly recommended that he stuff his brother into a specially made lightproof box and carry him around on his back. Yoriichi: "Got it." Michikatsu, stuffed into the box: "???" - One night during the Taisho era, beneath a sky dotted with stars, they met a red-haired boy carrying a box as well. The three people carrying boxes stared at one another. "So here's the question: who are you carrying in the box on your back?" - ◆ Lots of alternate-universe details, but I just really want to see everyone carrying boxes. ◆ The story opens in the present day, after reincarnation. The past-life chapters come later. In both their past lives and the present, Maika and Muzan are not related by blood, and both of them know they are not siblings by blood. - I recommend my friends' stories: "Yoshino Junpei's Nth-Loop Rebirth" by Qiuyuye: How many times do you have to die before you can truly grow? "After Becoming Gojo Satoru's Mother" by Lianqi: Mom's Beloved, mission accomplished. "The Jujutsu World Casanova Is Actually Me" by Limian: New flames and old loves collide in a passionate showdown. - I recommend my upcoming story: "Suture-Line Beauty [Jujutsu Kaisen]" by Qilong Banmu Fulan, whose medical skills are on a whole other level, has always believed she is an artificial human. The doctor told her she was created to benefit society and bring happiness to humanity. But one day, she met a young man with white hair and a black blindfold. The young man with the "Six Eyes" told her, "We used to be classmates, but you died during your second year at Jujutsu High." Banmu Fulan tilted her head in confusion, then raised a hand and tugged at Suguru Geto's sleeve. The suture marks on her arm and beside her mouth were plain to see. "What is he talking about?" The young man in priestly robes had a striking suture line running across his forehead. With his eyes closed and a gentle smile at the corners of his mouth, he said, "Maybe he's saying hello, to the 'us' who died." - ◆ The pairing is Fake Geto x Fulan. I love beauties with suture marks. There's something beautiful about them, as if they were pieced together or split apart. The cover features the two characters. ◆ Lots of alternate-universe details and utterly unhinged antics. Theme: Love means acceptance and forgiveness, one soul saving another.
