Bloodlines Online - Chapter 6: Path Of The Martial

Utsuro no Hako to Zero no Maria, or The Empty Box and The Zeroth Maria, tells the sinister story of Kazuki Hoshino, who is almost madly attached to his everyday life, and his antagonist Aya Otonashi, who suddenly transfers into his class—for the 13,118th time. She majestically announces to “break” him, without paying heed to anyone else around them.

Having crossed over into a world of Chaos and Order, brimming with all manner of bizarre items, Qiu Tu discovered he had actually slept with a VIP’s mistress... Since he had already been discovered, might as well... go with the flow? Strengthening his power, cultivating his influence, unearthing beautiful... and powerful subordinates, he steadily climbed to the peak of this world! Cataclysmic abilities and strange items included: the Cihuang Stone that could erase one’s impression from others’ hearts; a mythical beast’s head that could summon storms with a kiss; a piggy bank that could store emotions; a reversal potion that increased Favorability when hitting someone, and so on...

He was a wealthy and mysterious financial backer who had appeared before her when she needed money the most. After the courtship, she took the money and left.
