Chapter 100

The Immortal Army (不滅の軍団, Fumetsu no Gundan) is the 100th chapter of the Fumetsu no Anata e manga.

Summary
The Beholder narrates that Fushi allowed his feelings of rage to take over as he rampaged across the battlefield. Fushi learned his biggest weakness was losing consciousness. Whenever he started to feel symptoms of it (blurred vision and blood loss) he would immediately transform to recover. However, it only lasted five seconds before the symptoms returned. Thus, he transformed into countless of his forms in his fight.

A catapult in West Tower 9 catches fire and begins to fall onto the soldiers below, but Fushi stops it by transforming into Oniguma. Nokkers strike him in the back but he transforms away into Sandel.

While Fushi can't tell which forms are being stolen, he can tell when something is wrong. When he senses something wrong, he quickly transforms into Hairo to assess the situation. Hairo's body was more stable then the others (since Hairo can't feel pain) so he can lost longer without fainting and thus be able to concentrate on sensing the Nokkers. The downside to Hairo's form was that Fushi couldn't sense when he's been severely injured and that he can't sense the pain of those around him. Although he could push himself further in Hairo's body, it wasn't suitable for protecting himself or others.

In Kai's form, Kai's armour was suitable to block attacks from the Nokkers. Fushi could summon the secret weapon Kai made which allowed him to pierce through a Nokker's vessel to its core, destroying it, without first having to root out the Nokker.

In Messar's form, Fushi realized that Messar 's clothes were heavy because they held parts for a new weapon. Assembling the parts produced a new firearm Fushi's never seen before. The firearm could be continuously reloaded from within. Fushi summoned identical weapons for the rest of the troops who used it against the Nokkers.

However, none of the above turned the tide of the battle around. The Nokkers never attempted to scale Renril's walls, but instead seemed to be moving back away from Fushi's margins. While Fushi is distracted looking at a cannonball, a Nokker Oniguma made of rubble appears out of the ground below Fushi and chomps down on him. By allowing the soldiers to destroy their own Nokker-trebuchets, they were able to carve out spaces where Fushi couldn't sense them.

Fushi, still connected to his rope, dangles from it inside the Nokker Oniguma's mouth. Suddenly, the Nokker Oniguma crumbles apart and opens to reveal Messar, Kai, and Hairo standing above rescuing him.
