Ultraman: You Hit That Hard, and You Call Yourself Delicate?

Also known as "Otto: You hit someone so hard, you say you are weak?" [Reality + Game + Ultra + Cool Article + Semi-Invincible + Single Female Protagonist] (You get the Eternal Core at the beginning and use it permanently!) (The origin of darkness in the mid-term can be used permanently! All powers can be used permanently!) (´◊ω◊｀) (ૢ˃ꌂ˂⁎)٩(๑ᵒ̴̶̷͈᷄ᗨᵒ̴̶̷͈᷅)و( *ˊᵕˋ)✩︎‧₊ The outrageous Ultra journey started when he witnessed the incident of being beaten to death for stealing Q-bomb pudding. There is no way to explore the huge universe, but as everyone knows, the identity of "I" can be imagined. The ultimate dark Ultraman, why didn't I know it at the beginning? Even the King of Ultra is my uncle, so what kind of person is my father "Carter"? (In terms of plot setting, the timeline has been slightly adjusted, and there will be a story dedicated to the protagonist later, thank you!) [Bring your brain in later. I feel like my writing in the early stage was a bit confusing... (Of course, I can also bring my brain with me).
