Actually i'm too lazy to watch this anime because it have many season and episode but after being forced to watch it by my friend ngl, totally worth it. love the fight scene in the air using Vertical Maneuvering Equipment.

Anime Synopsis:

The plot revolves around Eren Jaeger and his childhood friends Mikasa Ackermann and Armin Arlelt, whose lives are permanently transformed when a Colossal Titan appears, causing the ruin of their hometown and the death of Eren's mother. Eren, Mikasa, and Armin join the Scout Regiment, an elite group of troops that combat Titans outside the Walls, vowing vengeance and reclaiming the planet from the Titans.
