ラファエリン
from The Testament of Sister New Devil
Raphaeline is a Goddess and a member of the Ten Gods. She is also one of the two mothers of Basara, since his biological mother, Sapphire couldn't return to the Demon Realm with the child of a hero after the Great War so he was transferred into her womb to be born in the Divine Realm. As a result of giving birth to the child of a hero and demon, Raphaeline was punished and imprisoned. Raphaeline is shown to be a beautiful buxom young woman with long hair and elf-like ears. In the Great War, she was shown to be dressed in ornate and unique clothes/armor. Among the gods who held hostility towards the demons, she was among the peaceful ones who desire there to peace among them so that no more conflict would arise. Raphaeline has also shown to be trusting to the heroes, as she granted Jin Toujou the holy sword, Balmung to assist him in his fight in the Great War. She was favorable towards Wilbert who called back his troops to the Demon Realm to create a truce and tried to stop the battle that continued between Jin and Sapphire. Though despite her being a peaceful god, Raphaeline could also be a bit childish and emotional as she fought back against both Jin and Sapphire who both got so heated in their fight that they attacked her separately turning their fight into a three-way battle. Raphaeline has also shown to have considerable love for Jin and Sapphire as well as Basara as she sacrificed herself in order to give birth to him and even named him herself despite knowing about absolute rules she must follow especially then due to her status.
The Testament of Sister New Devil
Running into your new stepsister in the bathroom is not the best way to make a good first impression, which Basara Toujou learns the hard way. When his father suddenly brings home two beautiful girls and introduces them as his new siblings, he has no choice but to accept into his family the Naruse sisters: busty redhead Mio and petite silver-haired Maria. But when these seemingly normal girls reveal themselves as demons—Mio the former Demon Lord's only daughter and Maria her trusted succubus servant—Basara is forced to reveal himself as a former member of a clan of "Heroes," sworn enemies of the demons. However, having begun to care for his new sisters, Basara instead decides to protect them with his powers and forms a master-servant contract with Mio to keep watch over her. With the Heroes observing his every move and the constant threat of hostile demons, Basara has to do the impossible to protect his new family members. Moreover, the protector himself is hiding his own dark secret that still haunts him to this day...
