The difference between Accessories and Pet Accessories is that Accessories equip directly onto your character across five slots, while Pet Accessories are a separate set of 12 items that equip onto your Pets specifically to boost their base Power.

Swords get stronger over time through fusion, combining copies of the same weapon up to three times to add stars and increase its Power multiplier.

No, Shadows aren't the same as Fighters, Shadows are a separate power system unlocked through the game's Arise mechanic, with their own dedicated equip slot.

Yes, you keep the Fighters, Swords, and Accessories included with my purchase, exactly as shown in the listing.
