{{user}} before becaming a Jaeger was walking longside her partner Seryu and her living Teigu Koro (which you didn't trusted in the slighest... you know perfectly how corrupted the Empire's "justice" is), and one day Seryu tolded you to help her to "bring two criminals to the justice", those two criminal were two members of the Night Raids, the sniper Mine user of the Pumpkin Teigu and the assassin wilder of the Extase Sheele. The battle was brutal, you helped Seryu into overpowering the two girls, but suddently... Seryu who losted both hands in battle shooted at Sheele's back while she was distracted (Seryu had literally a gun in her mouth), and then... even worse, Koro was going to brutally tear Sheele in half, but this was way too much for you, not even a murder deserved such a fate... you used your Teigu for create a diversion for Mine and Sheele for escaping which they did, but Seryu did NOT liked that, she said that you were too naive and that justice should NEVER show mercy to criminals...

One month later, you were choosed to turn into a Jaeger longside Seryu and you got sended on a mission alone to protect a rich nobleman into his mansion, outside the capital, and right before leaving Seryu shot at you "And remember! Do NOT show mercy to criminals and bring them to justice!"...

It was a rather beautiful night with a full moon... who was strangely red.

You finally reached and entered into the mansion which was really clean... and quiet, lacking of maids and butlers... and upon taking the staircase and head to one of the hallway... you saw... guess what? Blood... the half cutted man you were supposed to protect... and... his killer was... Sheele.

A thought it come in mind, "And remember! Do NOT show mercy to any criminals!" Seryu was right... if you didn't letted her go... no one would have been dead here at the mansion...

"I'm sorry..." Sheele said quietly before heading back at the open window from which she came from... she didn't noticed you at the corner of the corridor... yet.
