When Kira was slashed, Kanpei was
in Edo with his lord
Naganori. He went back to Ako in haste and suggested to
the others to hold the castle and to die for their lord. He
joined the "gimei "(to promise to revenge). The "Kanpei"
in the play "Okaru-kanpei" of "Kanadehon-Chushingura"

At a conference in the castle, Ohno-Kurobei and his son
Gunbei, who were both executives, verbally insulted
Okajima-Hachijuemon, an accountant officer, so they
were banished from Ako.

Kanpei also offered to take the priest's answer to Kira. In

Ohno-Gengoro also reported to Kuranosuke about the tea
party at Kira's residence, so Kuranosuke decided to commit
