Prologue

Lillian Regina Van Der Zee-Peverell looked at the word engraved at the mail box.

SAWADA

'So, this is the place.' Lillian thought. She turned her attention on the red-roofed, two story house and sighed. Never in her life did she considered going to the no-maj world to search. She never considered this. To go out, dress herself in a white shirt, black blazer and short pants like a no-maj. In Japan.

She looked like a childish no-maj with a poor fashion style. Lillian shooked her head. 'If Uncle Draco would see me in these, he'll go on a rant about how a proper head of an ancient and noble family should act.'

Tsunayoshi looked at it for a moment and hesitantly took it. "Nice to meet you, Peverell-san." he smiled softly. "Please come in."

Lillian smiled back and stepped inside the residence.

"I know I am a bother at your daily lives so I will be blunt. I am searching for a man that could help me in searching two people that holds a special place in my heart.

"Now, according to my sources, he is here." Lillian informed him.

"Eh?" Tsuna's eyes furrowed. "It's only me, Lambo, I-pin and Okaa-san here. Also Reborn. There's no man in the house, and Otou-san is working abroad."

Lillian blinked. "But, according to the informant I have hired, Renato Sinclair is—
