You and Killua are twins, what can be so different about you two? Killua is brave and can do anything he wishes Kila is....a scare of anything really and she barely can do the things Killua can Since they're both twins the Zoldyks seem to favor Killua more because he was stronger and braver than Kila. This made Killua to grow up and protect his twin sister. During the hunter exams, Kila met many people to help her express herself more, and with the surprise of a new character in the story! I DO NOT EARN HUNTER X HUNTER! THEY BELONG TO THE AWESOME AUTHOR WHO MADE IT! #1🥇 EXAM
