Ilse Kissling

"Humanity's World War II was...well, it was surprising to many. I remember I reincarnated with someone who was mostly not like-minded to me, but we did share one trait...our desire to instill fear."

- The Son

Ilse Kissling was a previous host of Mr. Tachibana, whom he reincarnated with in 1938 just a year before the Second World War. She was a former Wehrmacht soldier, and later a counter-espionage operative trained in psychological warfare, and was an expert in hand to hand combat. According to The Son, they both only shared one similar trait: the desire to strike fear into their enemies.

Eventually while he was with her, Ilse became part of Nazi Germany's black operations group Black Ice, which was where she became more than just a soldier. Using The Son's knowledge, she rose through its ranks and became an elite operative, and was respected by even regular German soldiers.

While part of Black Ice, she served under Hauptmann (Captain) Ernst Von Schnee, whom in turn served Oberst (Colonel) Peter Mathias Müller; a commander within Black Ice. However, after she revealed Mr. Tachibana's existence in her head, she was treated by Dr. Wilhelm Schultz in an attempt to purge him from her mind, though his attempts were unsuccessful.
