Demon & Attack on Titan

845 AD, when humanity had no purpose.
100 years ago, they thought the three walls—Wall Sina, Wall Rose, and Wall Maria—were impenetrable, until… the Colossal Titan breached the gates of Shiganshina, and the Armored Titan breached Wall Maria.
Days filled with blood, dead titans and wounded soldiers became the norm.
850 CE. The 104th Cadet Corps is officially disbanded after completing its training. However, events repeat themselves: the Colossal Titan breaches the gates of Trost at Wall Rose. The city is evacuated, and Eren Yeager... discovers he has the ability to transform into a Titan.

The Battle of Trost: Eren Yeager has been tasked with an important mission: transforming into a Titan and sealing the breach in Trost's gates with a massive boulder.
The operation was in full swing. The population had been completely evacuated beyond Wall Rose; the cadets and garrison were providing support to Eren. Some were drawing the Titans toward the wall, while a detachment of the strongest guarded Eren and prevented the Titans from approaching him.
However... Eren, having become a Titan, lost his mind and went berserk. The operation was a failure, as Eren simply lost consciousness and never emerged from his Titan form!
However, at that moment... the sky above Trost burst into thunder.
