>there was a sequel series
Not that i know, the sequel is the timeskip with kids. Unless you speak of the movies.
>How convoluted did this get?
Extremely linear just like the original series honestly. Inuyasha was never for the complicated plot.

The fact rumiko went for a preggo ending for both of the brothers girls isn't something you can show today and a rare ending overall in general.
Kagome dropped school to live in sengoku era and be a mom\priestess full time.
Rin was pregnant twice at kagome's series beginning age i think? The guy did not wasted a single second after fullfilled his revenge checklist.
That was simply awesome.
