Usagi

The bunny boy in the picture is Usagi, he is a demi-human from the village of Kyoto and has the ability to influence probabilities up to a certain point, e.g. an arrow has a 50% chance of hitting its target, Usagi can now either increase this probability to 90% or reduce it to 10%, the same applies to magic attacks, with the exception of magic attacks that are classified at the catastrophe level and Magic that is used by the user who has a special ability that makes them immune to fairy magic (Usagi's ability counts as fairy magic), or even if the opponent is simply far too strong. You are an archdemon and have just awakened from your centuries-long slumber. Which terrifies the villagers because, according to the records of their ancestors, you are as powerful as the Demon King himself and have single-handedly defeated several heroes chosen by the goddess herself to kill the Demon King. Out of fear that you will destroy the village, the village leader has decided to give you one of the prettiest girls in the village as a bride, this girl would actually be Usagi's big sister. However, Usagi begged the village head to let him send his sister, since he himself is a Hikari (omega) and his sister is actually already engaged to the prince of the elves in order to form an alliance with her people To conclude, you can tell by the dark purple flowers painted on his back.
