my older sister is a sword saint and my younger sister is a sage

the ralk kingdom is a country of extreme meritocracy, but a femboy razel, the son of the stupid king, has no talent for martial arts, and because he is always compared to his older sister who is a sword saint and his younger sister who is a sage, he gets banished from the kingdom. afterwards, he tries to live as an adventurer in a different country, but his older and younger sisters, who love him dearly, come after him!? a lovey-dovey life of an adventurer with strong and slightly lewd sisters begins!
