Party: Hida Ganko, Yoritomo Shohei, Doji Chi, Daidoji Jinsoku, Togashi Amajino.
The group reacted to the news of the opium store raids in the best way they could: they headed to the Temple of Osano-Wo (the Fortune of Fire and Thunder) to regroup with Yoritomo Shohei, but also grabbing Isawa Nagitoro (resident inquisitor) as a useful touchstone to figure out what they were dealing with in relation to Doji Chi.
Shohei-san was put to the question, oft repetitively by Ganko-san, and Kakita Michitaka (Cousin of Naritoki) gets called in to corroborate the story of Shohei-san.
Michitaka-san from his part, eager to help those who would fill the void left by the death of Naritoki, swears the group to secrecy before revealing Doji Chi's mother was Doji Tsuki, a powerful shugenja born outside of the Asahina family and a paramour who had gotten pregnant with Naritoki's child before the man came to perish.
Astute as they are, the party links the name Tsuki to the Moon, as it is spelled with the same kanji, putting the Cult of Lord Moon back at the fore of their thoughts.
The short version of Shohei's tale (with additions by Michitaka) which was revealed is:
When, in the dead of night, an unknown person boarded the vessel of Shohei's father (who was ferrying a senior member of the Kakita family with a cargo of goods for the man's dojo), Shohei's father drew his blade and ran through the interloper, thinking them to be a bandit or saboteur. This bandit turned out to be Doji Chi's mother - carrying her baby away from the captivity at the hands of Bayushi Korechika.
The Kakita suggested that, in order to cleanse the stain off of the hands of his old man, Shohei should bring the child to safety and ensure she could grow up the way she would have with a proper family - in Ryoko Owari, Shohei would likely find her relatives among the magistrates.
Considering all of this, and the threat of the Moon Cult looming in his mind, Shohei-san passed on the young Crane to Nagitoro-san and Michitaka-san, making them vow to keep her safe and in the gaze of the Statue of Osano-Wo at all times.
The group then headed out to investigate Watchful's warehouse (Jittu is a known merchant vassal of the Soshi family). Jittu seems ... fidgety, but takes GREAT PAINS to assure the magistrates know she's in the clear with her possession and sale of poppies and medicinal opium.
With what she told the magistrates, and what their own investigations turn up, following pieces of evidence are... evident:
*A Netsuki shaped like a coiled Scorpion with one claw raised is found trampled on the ground. (it bears striking resemblance to the Bayushi family mon)
*One of the attackers rode a large black horse with a white star on its head.
*Three guards were struck down, one from behind.
*The thieves piled a lot of the opium in a boat that was moored nearby and some of them sailed down the river to escape, while the others rode off on their horses.
*The Thunder Guard was not at the scene of the crime.
After this, the group decided to invite themselves (thanks to Doji Natsuki) to the wounded Ide Asamitsu and talk with him about the ronin Fade, whom they expected to have Unicorn Clan ties.
They did not get a lot of new information, but shared a pleasant talk with their host, leaving with the feeling that they had done well for the way the Unicorn viewed them.
At the end of day, Hida Ganko -with the party's blessing- went to place a short note at the Moon Caves for Fade to find, inviting him to reveal a meeting place to talk.
