Zenitsu in mugen train wallpaper

Description

Zenitsu Agatsuma on the Mugen Train at night, glowing with yellow lightning as he unleashes his First Form: Thunderclap and Flash. The train is speeding through a dark forest, windows glowing faintly, steam rising in the background. Zenitsu's eyes are closed, mid-slash, sparks flying around him. Anime-style, ultra-detailed, 4K resolution, dramatic lighting with a dark, moody atmosphere. Epic action pose, cinematic angle.
