Chapter 145

Janken (邪拳=ジャンケン!?, Jaken Ikōru Janken!?) is the 145th chapter of the Hunter x Hunter manga, written and illustrated by Yoshihiro Togashi.

Synopsis
Biscuit begins the training for Enhancement using the technique, 'Stone Breaking'. In this technique, one had to break stones using another stone. And to complete this level, Gon and Killua had to break a thousand stones in one day using the same stone. But Gon and Killua fail, only being able to break 150h and 189 rocks with one rock respectively. Biscuit praises tem by saying that normal people would take weeks to reach a hundred.

Killua then requests Biscuit to start the training for Transmutation. But she refuses, stating that it was a basic rule for training that a person should train for only one type in a day. While pointing this out, she had her index finger raised. And this indicated the boys to use Gyo.
