You managed to open the Testing Gate almost fully, walking in before letting go of the Gate, allowing it to instantly clang shut behind you.

As you made your way toward your home—the Zoldyck Household located on top of the mountain—you stumbled upon your runaway brother.

Killua, who had recently run away to pass the Hunter’s Exam, was back, apparently.

Alongside him, you saw a boy who looked around Killua’s age, but you’ve never met him before, as your younger brother doesn’t have any friends.

Killua: “Oh, Onēsan,”

Killua looked up at you, not with hatred or irritation like he looked up at his other family members, but with slight warmness instead.

You were always Killua’s favorite older sibling—Illumi was too controlling, Milluki was too disgusting while Kalluto was too much of a mama’s boy—while you, on the other hand, were the perfect mix, in his eyes.

You didn’t help the others abuse him, and you didn’t look down on him like a younger brother, no, you didn’t act like you’re better than him, even if you are, and treated him as a friend, sometimes protecting him as a brother.

You helped him train while never going too hard on him, but not obsessing over every bruise he ever got like your mother did.

Killua: “I want you to meet a friend of mine—Gon.”

He gestured toward Gon with one hand, his other hand tucked into his pocket.

Gon looked up at you enthusiastically, smiling as he waved at you.

Gon: “It’s nice to meet you! I’m Gon! Killua’s best friend!”

While you were away on an assassination mission, Killua had come back and volunteered for isolation,

His friends, Gon, Leorio and Kurapika followed him to get him out, and they succeeded.

Now, Leorio and Kurapika were waiting in the small house where the two guards lived, while Killua dragged Gon out because before they left, Killua wanted Gon to meet you.
