Does the manga ever identify who the father actually is? Or are we just supposed to assume it's some random guy that Masako had sex with?

@senshin I didn't put that in because I read this some time ago, and might have forgotten, but I don't believe we ever get to know him. It is certainly not the guy who is the father of Masako's second child (she explicitly says that).

<p>After watching the Series, I believe so, as no other figure appears, nor is mentioned.
I think it is safe to assume this is the case, as no other information is available.</p>

<p>In the beginning of the anime we're lead to believe that Daikichi's grandfather and this Masako woman are Rin's parents.</p>

<p>During the anime they confirm that Masako is Rin's mother, but they leave the father's identity up in the air.
If Daikichi's grandfather was Rin's father, he would have had to taken part in her conception at 73 years old - not impossible, but it's still a stretch.</p>

<p>Is Daikichi's grandfather <em>really</em> Rin's father? <strong>Is this revealed in the manga?</strong></p>

Is Daikichi's grandfather *really* Rin's father? **Is this revealed in the manga?**
