.Karuto.

Killua's younger brother. At first I thought it was his younger sister...but the Hunter's Guide says otherwise... Karuto joined the Ryodan for reasons unexplained. She herself seemed very homesick after she joined and wanted her brother...

.Milluki.



A.k.a: Miluki, Myllki
Killua's second oldest brother. Milluki is very fat and jealous of Killua. He is responsible for torturing Killua with whips and electrocution. Paradoxially, Killua could easily kill Milluki and threatens him often. When Killua escaped from home, he stabbed Milluki. Milluki is a computer genius, and has been looking to buy Greed-Island. Unfortunately, he can't afford it.

.Illumi.



A.k.a: Irumi, Yellmi
Killua's oldest brother. Killua is very afriad of Illumi for two reasons :
1. Illumi uses nen, which Killua found out about later.
2. Illumi used a needle to manipulate Killua, which Killua discovered while fighting the ants. The needle caused Killua to falter in front of strong enemies, including Illumi. I'm wondering if Illumi did this because he thought one day Killua would surpass him, and thus wanted to keep his powers in check.
