Oblivious to Love (Nanashi Mumei and Ceres Fauna x OC's)

2 male members join Hololive and were placed into the Holocouncil, however Ouro Kronii and Hakos Baelz were familiar with them since they were related. One is called Ouro Raijin, the younger brother of Kronii, unlike his sister he tends to be impatient and does things his way, he's also a huge sexist towards women. The other is Hakos Kage, he's just like his sister, cheerful, chilled and chaotic and plus he's not afraid to get bloody to satisfy his pleasure. What happens when 2 girls enter their lives, could they change?
