"A young woman from a minority people living in an underworld in which a different ecosystem from the Earth's one was formed. Since this peace loving girl became her clan's representative, conflicts have decreased and negotiations for a co-existence pact have been moving forward bit by bit. She has special abilities allowing her to understand space, even in the darkness thanks to a little light emitted by living beings, and she also possesses special equipment on her face which boosts this ability. The caterpillar that's always with her is her friend and was born on the same day."
The representative of her underground people, Esther is armed with a dagger and a Barrett sniper rifle. Her long range attack does decent damage and it's massive recoil causes her to be knocked backwards which also protects her from potentially fatal attacks. She is accompanied by a unique golden caterpillar in battle (name unknown).
Firing her rifle inflicts significant knockback upon her, moving her far away from the front line. She calls Grandee, a large golden caterpillar as her special. Grandee can block projectiles and can cover a large amount of range, but will stop if it hits an enemy unit or projectiles which normally delete others.
Should Esther herself be killed, her smaller pet caterpillar will perform one final charge, much like Machyna (the Red Goblin's drone) does.
