修女兽 天蓝 シスタモン シエル Sistermon Ciel
|首次登场||2018年1月 数码兽传说 网络侦探 黑客记忆（美版）|
A Digimon clad in a hood shaped like a mouse's head, it is the older sister to Sistermon Blanc and twin sister of Sistermon Noir. Unlike its sisters, it wonders the Digital World investigating abnormalities and reporting what it finds to Gankoomon. Its calm and gentle demeanor belies an unparalleled mental fortitude, making it a favorite among the other Digimon that happen to meet it. It carries guns called "T" in each hand, unleashing them in the silent but deadly special move Silent Bullet, and in the rapid-fire straight line special move Fury Fire.
