Honkai: Star Rail: Doubt It, Understand It, Become the Light

When Ultraman appears in the Honkai: Star Rail universe, the Astral Express Crew gains an Ultra Warrior. When the crew faces a great crisis, Lin Yu says, “So I stepped in.”

“If you dare lay a finger on the crew, you’re this” (thumbs up) “and I’ll let you get away with it” (pinky up). “If you can escape, you’re this” (thumbs up).

(When they reach Oandalos, the protagonist will also build an Ultra by hand.)

(No female lead. There’s no System at the beginning. The System only appears when they reach the Xianzhou.)

(I’m a new writer, so my writing may not be great, but I’ll take everyone’s suggestions seriously!)
