Toaru Majutsu no Index - Volume 11, Chapter 2: The Preparations for going to London. Un_Frammento_di_un_Piano.

For three years Calix suffered from the Backlash of his undecipher Term Attribute. As he couldn't use his unique power, he went through series of misfortunes which caused him to lose his self-esteem. However, one day, he was caught in an incident that led him to awaken his hidden power(luck).“The fuel of my Term Attribute is sexual practices with the opposite gender?”

The protagonist, Winnie (文尼), confesses his love to his childhood friend—the princess he’s been secretly in love with for years—but is brutally rejected in public. His heart shatters, he’s humiliated and ridiculed, and he collapses unconscious. When he wakes up, he vaguely remembers his past life’s memories and realizes he has transmigrated into the world of an otome game he played before. At first, he’s thrilled, thinking, “Nice! I must have been reincarnated as a villainous side character who disrupts the protagonist’s romance, right?” But then… surprise! He’s not just the villain—he’s the “Saintess”!

Liam Sera Banfield is a reincarnator.

He was reincarnated into a fantasy universe of swords and magic, but at a time that civilization was already making advancements into outer space.

The setting takes place in an intergalactic empire, a space opera-like universe where humanoid weapons and spaceships do battle.

Liam, who had incarnated into an aristocratic family in a monarchic society, has the ambition to one day become an evil lord.

In his previous life, Liam had unfortunately lost everything and died in despair.

— It’s foolish to live for others.

— I will live for myself.

Holding those feelings in his chest, he starts towards his second life, but is instead worshipped as a virtuous ruler from his difference in values.

Will Liam be able to safely become an evil lord?

The most unlike Slytherin.

There is a saying in the Slytherin common room, “The little wizard who disobeys will be eaten by the Night Stalker.”

He is the master of the stars that shines at Hogwarts, the Night Stalker who is feared by his enemies.

The glory made him the pride of Slytherin.

When the Dark Lord arrived, he said those words,

“Weapons, I need a lot of weapons.”

With a staff in his left hand and a sword in his right hand, everyone would shout for him: “Damn the Sorting Hat, is this Slytherin?”

When the stars return to Hogwarts, John Wick’s light will shine on the entire wizarding world.
