Type Moon and Jack the Ripper?

In this flawed copy, since Jack was already bloodthirsty, somehow turning her into The Berserker actually resulted in the opposite. She is now completely calm. Since nobody knew who Jackie the Ripper was, Jackie can shapeshift into any legend of Jackie the Ripper she wants to be. Her master is a doof, who used a toy knife to summon her. However, a Fake knife in a Fake Grail War worked just fine to summon a Fake Berserker from a Fake Hero.

The Maestro was completely baffled!!!!!!!!!!!! A berserker could actually be calm and collected??? Then she remembered Paul's former servant, Frankenstein.......of course........Frankie was calm and collected too........she tried to do countless research on Jackie the Ripper but she couldn't find anything!!!! She tried finding stuff on Type Moon; however, she couldn't find anything on her either!!!!!!!!!!!!!!!!!

Their sizes are completely unknown!!!!!!!!!!!!!!!!!!!!
