Maybe that is why Kim-hyung have the sect master complex every time.

Haki

Nope. that is gentle step twin lion fist. It is one of the highest form of gentle fist created by hinata and seems to be only her original. That is only visual effects like guy morning peacock or daytime tiger which a chakra take form. I thought it was some form of yang release before but after researching it turn out that it is achieved through high mastery of chakra control and manipulation.

No. Gentle Step Twin Lion Fists is a Hidden Taijutsu derived from Gentle first of Hyuuga. Hinata has to me a perfect chakra control, that lead her to master the Main branch only gentle first technique. Think of it as advance gentle first. The skill effect is only from chakra manifestation not yin, yang or nature transformation. Just pure chakra like when Guy use his technique when opening gates (weaker than Guy jutsu ofc).
