Wang Dian somehow transmigrated to Japan during the Warring States period, in the late Muromachi shogunate era. He became Tianjing, a young monk of the Jodo school who was following his master on the way to Ishiyama Hongan-ji.
He also transmigrated with a bizarre "Causality Weapon Arsenal System." This System allows Tianjing to temporarily "graft" the signature abilities of famous historical and fictional characters onto himself.
Tianjing (Yan Shuangying): I bet your guns aren't loaded!
Tianjing (Lu Bu): Lord Imagawa Yoshimoto, renowned archer, are you sure you want to take me as your adopted son? Then I won't stand on ceremony. By the way, I hear you recently took a new concubine...
Tianjing (Edogawa Conan): There's only you and me in this room. Tell me, which of us do you think will die today?
Tianjing (Huang Laoxian): The Takeda army looks fierce as fire and moves like the wind. They must be hard to deal with... Hey, do you think there's something odd about their horses?
Tianjing (Boruto): Burning down Honno-ji? Burning down Mount Hiei? Is that all you've got?
