I crossed into the world of Type Moon and, for some reason, the Root itself recognized me. As long as I die an abnormal death, I can ascend to the Throne of Heroes and become its lord, an existence stronger and freer than even the Seven Grand Servants. So, in order to die, I started acting like a complete fool across the Nasuverse. I cursed Gilgamesh to his face in Uruk, challenged almighty Zeus in Greece, openly kidnapped Skadi in Northern Europe, proclaimed in Israel that Solomon was a demon god instead of a holy king, and even stood at Morgan's side in Britain. Yet for some reason I am still alive. By 1994, Fuyuki City, history has given me a ridiculous list of titles: the third friend of the Most Ancient King, the first prime minister of Mesopotamia, the man favored by the Greek gods, the king of giants in Northern Europe, the incarnation of God who awakened Solomon's humanity in Israel, the miracle worker supported by Prince Camelot. On top of the Fuyuki Bridge, a young yet world weary Lovi sits on the railing, staring at the city lights and sighing. "Tell me, what exactly went wrong? Or you could just kill me here and let me finally ascend to the Throne of Heroes. Please." Kiritsugu Emiya lights a cigarette, glances at Artoria holding the Holy Spear, at the treasury of the King unfolding beside Gilgamesh, at the crimson spear tip reaching out from the distant Kingdom of Shadows. The cigarette in his hand trembles slightly.

After transmigrating to the Douluo Continent, Yu Tianlin awakens the Blue Lightning Tyrant Dragon Spirit and steps onto a path meant for legends. But fate throws him a curveball. His first Spirit Ring comes from a Thunder Hell Prison Vine, a Spirit Beast that should have been ordinary. Instead, it leaves him with a rare external Spirit Bone that can draw lightning and devour thunder. Each strike of lightning refines his Spirit Ring, pushing its age higher and higher, breaking limits that Spirit Masters treat as iron law. With thunder as his forge and willpower as his hammer, Yu Tianlin begins to carve out a new future. He will rebuild the glory of the Blue Lightning Tyrant Sect, challenge the storms gathering on the continent, and recast the path of the Thunder God with his own hands.

After reincarnating into the world of Naruto, Yami awakened the Bond System, a power that grants him rewards for forming connections with others. Good news: he has a cheat-like ability. Bad news: his name in this life is Shimura Yami, and his grandfather is none other than Shimura Danzō. As he stared at the long list of enemies, so long it couldn't fit on a single page, Yami could only sigh. Forget about being a carefree playboy in the ninja world. If he wanted to survive, he'd have to go full menace mode.
