Mo Ran--by mistake, he was imprisoned in the palace on behalf of the Leng family, waiting to marry into the royal family when he was sixteen.
Jing Han - was born in the Leng family, without a father or a mother, and was raised by his master. Although he had a blood feud, he only wanted to save Mo Ran from the palace.
The bond between the two is not only that, but also includes the country and interests.
Jinghan's setting will be a bit like Saber, justice, integrity, stubbornness, and a bit dull.
Sumizen's setting will be based on some of Aragaki Yui's settings, the goddess of vitality, but also a bit of a royal sister.
I just love Yui Aragaki and Saber so much! ! ! !
