User blog comment:FrankieX98/The future members of the Issei's harem and peerage./@comment-2601:87:8300:20D0:9120:68D5:653A:9CC0-20181222144600/@comment-2208155-20181222152938

Sometimes I am doubting but... After this tweet(mentioning again that Roygun and Yasaka are popular and.. specially the last part of this tweet that sounds like if he is really adding them in the harem):

And another older tweet saying something about Roygun and Yasaka development(why yasaka needs development?) I am inclined me to believe this

'''No matter.. I am sure about Roygun chances.. About Yasaka Shin dxd 3 will show if she has chances or not..'''
