So, now we've solved the entire mystery of the first two fictions - The Lion Clan poisoned Doji Satsume, it took Hotaru a few weeks to work out who it was, so she went off to execute the Champion of the perpetrator's Clan, since one cannot live under the same sky as the man who killed one's father.

Also fits with the well-known fact that Fumio the cat is the one who killed Satsume, since cats are basically small lions.
