[Genshin Impact] Electro Diffusion

"There will always be beings on this earth who dare to face the glimmer of lightning." A razor-sharp blade swept toward him in an instant, carrying the force of a thousand thunders. His hand moved faster than his eyes, raising his katana to block the attack aimed straight at his neck. Stinging pain spread across his face: the lingering force of the blade's aura. I can't block it. I knew it with absolute certainty. Is this... Musou no Hitotachi? The katana snapped. The last thing he saw before losing consciousness was a pair of eyes filled with grief and disbelief. "Kazuha's eyes look so much like red maples in autumn. They're beautiful..." "So, I'm really just an ordinary passerby." The friend, who had suddenly been dumped at what appeared to be a crime scene with his mind blank and a broken katana hilt in his hand, felt he could still be saved. A spontaneous idea after watching the PV. As everyone knows, a bosom friend is the same as a beloved, hehe. The CP is Friend x Kaedehara Kazuha. There's also a side CP, Gojo and Geto. In a way, both are widower CPs, aren't they? OVO (Why the hell?) Theme: Humanity's anthem is an anthem of courage.
