The story began with a conversation in the cafe between the Commander, SG DP-12

, RF Carcano M1891Carcano M1891 
, and RF Carcano M91∕38Carcano M91∕38 
about Internet Soul Eater. DP-12 sang a song about her, and Carcano M1891 complemented the rest. The frightened Carcano M91/38 tucked onto Commander's arm, before she ran away. Feeling bad, Carcano M1891 excused herself to after her little sister, and so DP-12.
It only took two minute before the Commander was surprised by an alert from DP-12. She found both the Carcano sisters collapsed in front of SG S.A.T.8S.A.T.8 
's room. Their battery charge level was adequate, but DP-12 couldn't bring them to surface level consciousness. Both S.A.T.8 and SG SPAS-12SPAS-12 
were found collapsed inside the room. And so the Commander and Kalina have been investigating this strange case for a week. All the Level II technical staffs were on vacation, thus there was not much progress made by the two.
