Princess Principal, Spy Girls Fight in Old London

Princess Principal take you on a journey with unusual young girls as they conduct espionage, all types of spy work, and even engage in assassinations. This is another take on the cute girls doing dark things. I am getting flashback of Madoka Magica. Tanteikid, you have made a mistake. Oh Then you explain it. Warning, there a few hints of yuri undertones that sensei might not have mentioned.
