I Bound Myself to the World-Destroying Final Boss

Ryugu Nana reincarnated into the world of an urban fantasy game she had played in her previous life and obtained a Binding System. She could bind herself to a single target, and her own superpower would automatically rise to match that target’s level. And so, armed with memories from her previous life, Ryugu Nana chose Nanami Orihime, the final boss destined to destroy the world seven years later, as her binding target! ————— “Whenever I run into trouble or feel discouraged, Ryugu Nana always appears to encourage me and gives me the motivation to keep going. She’s always so gentle.” “Whenever she gets something that can strengthen superpowers, she immediately shares it with me. She says she saved some for herself, but I eventually realized that she never keeps anything. Why is she so good to me?” “She uses even fewer resources than I do, yet she’s no weaker than me. Her talent is clearly greater than mine, but whenever she obtains anything useful for improving superpowers, she gives it all to me.” “She tells me not to be afraid of hardship because she’ll always stay by my side.” “Waaah, Ryugu Nana, you’re so good to me! How could I ever repay you!” Nanami Orihime felt that Ryugu Nana was a ray of light illuminating her dark life. Ryugu Nana: “Don’t be like this… I’m starting to panic.”
