Shiro Butahi Sairaiden: Koukyuu mo Nidome nara

Zhu-Li, the "White Pig Princess," was exiled from the palace and banished to the red-light district under false accusations. She was forced to live poorly, but she was able to lead an unexpectedly fulfilling life under the protection of Reo, the young head of the slums. She was polished by hardship to become a new person, an immensely beautiful woman! So much so that she was kidnapped and brought back to the palace.

However, her escape attempt backfired, as the worldly skills she had developed in the red-light district and the slums came in handy. So much so that she was recruited by the ruthless general Kaku to become a candidate for queen...?
