Shikotsumyaku.

[Zzz]

Is there a chance that Hamura also possessed Shikotsumyaku (the bone techniques) just like Kaguya?

 

[DrProof]

Possibly .

 

[Ashura San]

Hago or Hamura had to. The ability had to be passed down.

 

[Gerkak]

It is possible.

 

[Young Vongola]

Probably. It's not impossible

 

[9bi]

It's probable.

 

[Ansatsuken]

Nah, it just unique to Kaguya only, no scond or third. Choose your own power instead.
