Rising in the shield hero world with a omni-verse shop

Embarking on an anime-themed transmigration wasn't exactly how I envisioned my life's journey, but hey, let's roll with the unexpected twists, shall we? Oh, and guess what? I've got this incredible Omni-Verse Shop in my cosmic toolkit allowing purchase of knowledge, skills, items, abilities, summons and creatures. It's like where I can snag items from various universes. Pretty cool, right? Let's see where this wild ride takes me! Warning-This is my first writing a novel and English is not first language and I am using ChatGPT to correct the English. All the character except OC and few new I am planning to introduce later other than this all belong to Rising of the shield hero anime and their respective owners.
