I'm Martell, a winery employee... Watered wine, codenamed Martell.
I once lived in Hogwarts Castle, but after three years of great sorrow and joy, dementors attacked this "safest place in the wizarding world".
One of the castle's shields was breached and I passed out.
When I wake up, I become Martell in the winery.
I took a deep look at my level 45 magic book and few gold cards, and started to think seriously.
You said I survived until the finale... Is this possible?
1. Water water water
2. Self-pleasure and collapse of character
3. Protagonist, after all my magic has awakened, am I still invincible? (Bushi) (Whether I am invincible or not depends on how high I am)
4. High probability of pitfalls
Purpose: Live and have fun
