I think this is mixed up. I think “Ren” 2.0 (I hate that there’s so many damn dupe name people) is actually Reira’s (?) kid w/ Shin. Appearances at least suggest that he looks more like Shin than Nobu. Iono. ╮(￣▽￣)╭
So basically, in chapter 70 it's revealed that Hachi first born is in fact a boy named Ren (I believe he's Nobu's child after seeing him) and she went and then had a daughter with Takumi?
I'm sad that we'll never know for sure about this
