Dimensional Breakthrough: I Can Control Vectors

Stories About Accelerator or Vector Manipulation

Something in the vein of A Certain Scientific series.

The Protagonist Can Open Portals to Other Planes, Including Anime Worlds, Elemental Worlds, and Novel Worlds

Something like "Myriad Worlds Exchange System" or "Urban Wanderer Across Myriad Worlds."

Looking for a Novel Where the Main Character Has Conceptual Powers

Urban supernatural powers or a supernatural resurgence, with conceptual abilities like being able to catch a blade with your bare hands every time.

Any Stories Where Characters Draw Powers from Anime and Manga?

Fate, Gilgamesh, the Golden King, and Gate of Babylon

There are far too few stories about Gilgamesh. I really like him, but there aren't many stories about him. I'd love recommendations for good ones, whether the protagonist roleplays as him or gains the abilities of a king. Thank you, and may your whole family be blessed with wealth and good health!
