[Your Traveling Frog has returned home and brought you a local souvenir: a Mythical Zoan Rubber Fruit!]
As the young lord of Inazuma and the adopted son of the Raiden Shogun, he finally escaped the storm-clouded nation after the Vision Hunt Decree upheaval.
At the very moment Paimon fished him out of the sea, just when he thought his life was hopeless, he finally heard the frog's clear, melodious croak.
The Traveling Frog, protagonist of a mobile game from his previous life, had appeared before him. It would travel around different worlds, and sometimes bring its owner souvenirs from those other worlds.
The Demon King talents from the world of Campione!, Chaldea's Noble Phantasm, a blue spear-wielding Lancer, and Ranma's Spring of Drowned Girl.
And that's not all. Friends from other worlds, including Academy City and Chaldea, would often come to visit.
[Ding! Your friends, the Railgun quartet, have come over! Please treat them to some of your souvenirs!]
After quelling the Stormterror crisis and the Rite of Descension in Liyue, Nanga Ye once again set foot on Inazuma's soil.
In the Plane of Euthymia, facing the Raiden Shogun's thunderous Musou no Hitotachi, Nanga Ye proudly drew the Tengen Sword in his hand as well.
