Reborn in the Eighties: I Won’t Be Ruled by Love

The Protagonist Becomes Noa, Able to Use Ultraman Noa Infinitely from the Start

The protagonist becomes Ultraman Noa from the start. Not someone who just gets a few fragments, and not a form they can only use a handful of times: they become Ultraman Noa permanently. A System is optional.

Any Sweet Period Novels Without a System?
