I really think the short description gave you what you needed to know, but if not:
This is a re-write of the S4 battle between Twilight Sparkle, and Tirek; won't be focusing on the after-battle scene, nor the major build-up. This will take place from the point of the tree's destruction. I wanted to animate this, but I need time to practice in OpenToonz.
Though, dunno if "anime-style" fits the description; didn't make them monologue for 5 chapters.
Wait...the battle wasn't anime enough. XD Sorry wanted to say that; do plan to read it.

Lol. Yeah, it was just something I had to do, otherwise my brain would be filled with the idea for days, lol.
