Buru-buru frost youkai looks like Granny Sand but with a frozen attributes, a bit similar.....😅
It was indeed a brave act by Yuta to save her dearest friend & someone that he considered to be his own sister & family, Mana right after Buru-buru clutched her by Mana's throat!
Im sure Mana would be very touched by his heroic act!!🌟🌟
