Bowlroll Password Assistance

Genitsu

Momo's Minion
I completely understand the pinned thread, but I've been trying for 4 or 5 days now on this model and I'm at my wit's end. However I did read the artists terms and conditions and I'm willing to abide by them and not break any of the rules. I have no intention of stealing any of this model's assets and using them/posing them as my own. All that aside.

I need help finding the password to this model: https://bowlroll.net/file/208186
This is the password hint: Password: his Ikute surname (two Chinese characters) or パスワード:彼の育手の名字(漢字2文字)
From what I know so far, his surname is Agatsuma, but he also an another surname, which is Azuma.
Both of his full names are Zenitsu Agatsuma and Yoshitsugu Azuma
Here's the link to the blog where the model's download link and terms are: https://ch.nicovideo.jp/tututututu/blomaga/ar1693759
Here are the characters I've tried so far: 善逸, 我妻, 上妻, 妻子, 柳沢, 吉保 None the these worked though unfortunately.

Any help is greatly appreciated!
