Luini

Louisny (ルイ＝ニー, Rui Nī) is a member of the Heil-Ly Family.

Appearance
Louisny was described as a man of slim build in his twenties, between 185 and 190 cm tall, and with a large crescent-shaped scar on his left cheek. He has prominent teeth, a high brow and fair, combed-back hair.

Personality
Louisny is a ruthless killer. He murdered 20 people in a short span of time, and later killed another as a "prank" for the Phantom Troupe, for whose fearsome power he feels an intense feeling of adoration. Like his leader, Morena, he appears to want to destroy the world.

Succession Contest arc
Louisny willingly boards the Black Whale to follow Morena, who kisses him to activate her ability. Louisny disguises himself with a Kakin soldier and goes on a killing spree, murdering 20 people in Tier 3 with an edge weapon. He next appears in Tier 5, spying on Nobunaga, Phinks and Feitan while they are inside a warehouse. He swiftly grabs their guide, slits his throat, and drops him behind them. When they ignore his actions, Louisny admires their composure and wishes to destroy the world with them.

Abilities & Powers
Louisny was able to kill 20 people in a short amount of time with an edge weapon, which suggests a certain amount of skill. He appears to be quite fast, snatching the Phantom Troupe's guide inside the warehouse in a split second.

Nen
Having reached level 21 with Morena's Nen ability, Louisny's aura amount and output have been increased. He also obtained a Hatsu ability. He displayed the capacity to open gashes into the fabric of space, seemingly by connecting different surfaces. It is currently unknown if that is the ability he received from Morena or if he developed it himself.

Trivia

 * His surname (ニー) is very similar to the Japanese numerals for 2 (二) and 1 (一). Coincidentally, 21 is his level at the time of his introduction.
