(Crossover, Mainly Home Tutor) When Yin Falls, Yang's Sky

Literary version: Legends that cross between yin and yang belong to those called "Onmyoji." Legends that traverse time and space belong to those called "Magi." Beneath the boundary between sorcery and magic lie the secrets of the past, present, and future. At the call of yin and yang and the six realms, the two will join, and their master is about to appear── Crack-up version: As the only treasured daughter of the Abe family, she is mischievous by nature, has a scheming streak, and aims to level up into a wicked little sadist-- Abe Iro lowered her head gloomily, clenched her fists, and said with deep regret, "Tsuna was useless back then, but he was so innocent and guileless that you couldn't help wanting to tease him--like a pure white rabbit! But he's leveled up way too fast now, and looks like he's about to surpass me... That rabbit isn't just black now, he's turned into a wolf──" "Luo Luo, you're not feeling well. Come on, let's go back to our room and talk~" Sawada Tsunayoshi, ten years later, walked up to her with a gentle smile. He scooped Abe Iro up in his arms without giving her a chance to resist, carried her back to his room, and planned to discuss the future of their lives. Biting her handkerchief and weeping silently, Abe Iro thought--the worst thing she'd ever done was turn Sawada Tsunayoshi into a schemer, and she hadn't even realized it. She'd practically sabotaged her own family! The male lead is destined to be 27. Tsuna is pretty useless at first, but later on he is subtly influenced by the heroine into becoming the ultimate embodiment of a schemer. Of course, that doesn't happen until ten years later~ It's definitely a crossover. This is the second entry in the Time and Space Rules series. The heroine is an original character, neither a transmigrator nor a reborn girl. Her powers are yin-yang arts and magic, and the 73 are involved too. Well, it's a growing-up story~ Updates are irregular. If you like it, please add it to your favorites~ Slow updates. Mom is out of the hospital, so I'm working hard at my job and writing this story (beaming)
