Which ones is she talking about, by the way? Mari, Ami, and now Kagome are the obvious ones, but who else?
- Akane? I'm not sure Kei's initial hostility towards her counts as "being estranged from a family member", though – I'd say it's more that she didn't consider Akane a family member up to a point. And past this point, I don't think they had any notable falling-outs...
- Noburi? He'd reacted very poorly to Kei blurting out a statement that could be interpreted as her only caring about Mari, way back when, but I'm not sure it was anything as bad as being estranged.
- Hazou? She'd reacted very poorly to our absolutely brilliant Ami Date plan, way back when. I think that arguably could be counted as (very brief) estrangement?
- Shikamaru? He'd screwed up with his marriage-sealing announcement at the Chuunni Exams. But much like with Akane, I'd characterize it as not counting as family at first...
- Snowflake? Again, it's more like she wasn't family until she was, not that she was estranged.
- Jiraiya? He's kinda still estranged.
- Anna? But I don't think Kei got the chance to finish vivisecting her, so she's still estranged.
Uhh. Hm. What other family members does Kei have?
