■Succubus Astrea the holy mother knight (human form) Although she has been transformed into a succubus by a curse, she has not lost her sanity due to the blessings of the spirit and her will as a mother, and she is almost the same as the previous Astraea, except that she spoils Kain more than ever. She usually hides her wings and tail, but her breasts, which have grown two times larger, cannot be hidden. Her mother's milk, which is now flowing again, is holy milk that gives the power of spirits and it has become a habit for her to breastfeed the hero Kain before he goes to bed. Also, the morning and evening greeting hugs and kisses are deeper.

■Astrea, Liliana, and Ophelia have been cursed to become a succubus. Although they were able to avoid full Succubusification, they still have to find a way to break the curse. The succubus transformation has made them less reluctant to expose their skin to the public, preferring to wear assertive equipment.

■Kain the hero His mother, sister, and aunt have been cursed with the Succubus curse and he is painfully aware of his own lack of power. It is a blessing in disguise that they did not turn into succubus completely, but they are now wearing sexier equipment and are even more clingy than before, which makes him feel frustrated that men on the street look at his mother, sister, and aunt in a dirty way, and he is confused as to what he should do.

■Succubus Liliana the Fencer (Human form) She was turned into a succubus by a curse but came to her senses at the call of her brother, kain. Normally she hides her wings and tail to maintain her sense of reason, but perhaps due to the effects of her succubus transformation, she has returned to her old mischievous nature, and she plays pranks on Kain that are akin to sexual harassment, such as trying to make him put on her underwear. Moreover, it seems that "Liliana when she is in a good mood" has become her true self, and she is always close to Kain. She started to greet Kain with hugs and kisses in the morning and evening, following her mother's example.

■Succubus Ophelia the wizard (human form) She was turned into a succubus by a curse but came to her senses at the call of her nephew, Kain. Because she used to be a magician, she is more proficient than the other two in succubus lewd arts such as charms, which she learned through her succubus transformation. Her wings and tail are usually hidden, but her bust is enlarged and oversized. She is troubled by the fact that her areola, which was large, to begin with, has become even larger. Probably due to her succubus transformation, she is completely attracted to Kain as her opposite sex and wants to make him her husband when they return to their hometown.
