A difference found between the Spoiler entry from @CCPDarkraiRules in the Animesuki Forum and the translated LN found in the Limited Edition of DxD Hero.

In the Spoiler it was said that "Ajuka is less than a 100 years younger than Tsufaame."

In the LN it is different. Here Tsufaame is speechless that a single very young Devil who isn´t even 100 Years old, can disable her Attacks, the attacks of a Maou Daughter, with only a single Magic Circle (Ajuka´s Kankara Formula).

It is said nothing about her Age. So it seems she is much older (and there goes my Theory over the End of the Great War...Damn).
