Described as a hotheaded, hyper-sexual juvenile punk, he is easily annoyed, quick to lose his temper, and his juvenile actions often get him and others into trouble.

Despite this, he is supposedly good at looking after new members, and so was assigned as Leo's partner/bodyguard. He is also something of a ladies man, possessing several lovers in town.

For reasons unknown, he continuously tries to fight Klaus, only to be routinely smacked down.

A breach between Earth and the netherworlds has opened up over the city of New York, trapping New Yorkers and creatures from other dimensions in an impenetrable bubble. They've lived together for years, in a world of crazy crime sci-fi sensibilities. Now someone is threatening to sever the bubble, and a group of stylish superhumans is working to keep it from happening.

Three years ago, a gateway between Earth and the Beyond opened in New York City, trapping extradimensional creatures and humans alike in an impermeable bubble. After the city's restoration, monsters, magic, and madness are common findings in the area now known as Hellsalem's Lot. Leonardo Watch, a young photographer who unwillingly obtained the "All-seeing Eyes of the Gods" in exchange for his sister's eyesight, came to this paranormal city to find answers to the mysterious power that he possesses. He later finds his life drastically changed when he joins Libra, a secret organization of people with supernatural abilities dedicated to maintaining order in the everyday chaos of Hellsalem's Lot. 

However, this is only the beginning of Leonardo's unexpected journey ahead. Regardless of the constant threat of otherworldly enemies, he is determined to uncover the secrets of his power and find a way to restore his sister's eyesight. Kekkai Sensen & Beyond follows Leonardo as he sets off on more crazy adventures with his comrades, fighting to ensure peace and order.

Three years ago, a gateway between Earth and the Beyond opened over the city of New York. In one terrible night, New York was destroyed and rebuilt, trapping New Yorkers and extra-dimensional creatures alike in an unassailable island, a world all its own hidden in the mist of its physics-defying waterfalls. 
New York has been rechristened Jerusalem's Lot, a paranormal melting pot where magic and madness dwell alongside the mundane, where every form of human vermin gathers to exploit otherworldly assets for earthly profit. Now someone is threatening to breach the controlled flow of unharmful, average humans and items in and (much more rarely) out of the city and thereby release Jerusalem's Lot's deluge of horrors on The Outside. The mysterious super-agents of Libra fight the impossible to prevent the unthinkable.
