User blog comment:DreiAcosta/What do you think are the other nen conjured weapon of kite by his crazy slot??/@comment-5780397-20141222140457

Being reborn as a member of the Royal Family, I think he will get much stronger in the future... I think at least one of his other weapons is a katana, like the one he carried at the start of the series, because it would make no sense for him to stop using it if he can have nine weapons. My guess is it is Number 1. Then... speculation time. There might be an old blog on this topic, if I remember correctly.
