MTL - First Law - Chapter 450 birth hole

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.

Transcend to become the prince of Daxia, activate the Devil Emperor Summoning System, summon the powerhouses from other worlds, and fight for hegemony in the heavens!

If I were the Devil Emperor in the future, I would definitely let your blood stain the sky!

That night, she shed off the image of a young maiden’s immaturity, forming a ripple in the deepest parts of the Cold Palace…

That day, she kneeled before him begging for mercy. She didn’t want anything. She only wanted to leave the palace and become an ordinary girl….

A bunch of elegant and good looking heavenly princes. A lowly palace maid with a mind as calm as still water.

A spin-off of Lillia and Treize, Meg and Seron is a high school adventure/mystery/romance/comedy of sorts taking place in the rough equivalent of the 1950s. The story follows Seron, a stoic and handsome bookworm who is in love with his classmate–a sweet, oblivious transfer student named Meg.

Meg and Seron takes place at around the same time as Lillia and Treize, but knowledge of the main series is not necessary to read Meg and Seron.
