Incubating Catastrophe (災禍の胎動) was a story event in Assault Lily: Last Bullet. It ran from 2021/7/10 to 2021/7/25. It is playable as the second part of main story Chapter 1 afterwards.

Introduction

With the sudden collapse of the Area Defense, the Tokyo metropolitan area is plunged into chaos by the swarm of countless HUGEs.

To overcome this dire crisis, the Lilies across the city—including Team Hitotsuyanagi, Hervör, and Gran Eple—unite and fight desperately to hold the line.

In the midst of this turmoil, Gran Eple engages in a fierce battle against a mutated HUGE. Though they struggle against its formidable strength, they eventually manage to strike it down. However, their victory is short-lived; another HUGE arrives to consume the fallen creature's body, giving rise to a newly evolved, mutated HUGE.

Faced with an endless and desperate battle, the Lilies continue to fight to protect the people.

Summary

Don't you dare say this is the "end," okay? Because after this, Gran Eple's... no, our battle will continue.
...This time, I will protect everyone. Takane-chan... and all of my precious comrades...
Everyone, lend me your strength! As Gran Eple, we are going to take this enemy down...!!

—Kon Kanaho, Incubating Catastrophe, scene 1-6

Prelude: Legions, Assemble

LG Gran Eple engages one of the three mutated HUGEs during their combat, quickly discovering its ability to adapt and learn from their attacks. Although the legion manages to strike the creature down using feints, the HUGE summons reinforcements before expiring. A second HUGE of the same type arrives and consumes its fallen comrade, merging into a Large-class in size but with superior firepower and intelligence. Gran Eple attempts a Neunwelt tactic, but the attack is neutralized by a Magi-Reflector, leaving the Legion in a desperate position.

As they struggle to secure a retreat route, Team Hitotsuyanagi and LG Hervör arrive to provide reinforcements. Futagawa Fumi suggests utilizing wave attacks to prevent the creature from adapting to their patterns. Overwhelmed by the assault, the heavily damaged HUGE retreats to the top of the Tokyo Metropolitan Government Building, encasing itself in a protective cocoon.

To destroy the cocoon before the HUGE can finish incubating, the three legions execute a Neunwelt tactic. However, the Magisphere remains hindered by the Magi-Reflector just as the HUGE completes its metamorphosis. Faced with this crisis, Hitotsuyanagi Riri activates her Rare Skill, Charisma, to maintain the battle; The skill's output reaches an abnormal level. However, a powerful beam from the HUGE interrupts the fight before it can be decided, leaving the battlefield in total chaos.
