豆籾 平太

Raiten Menimemo was a Japanese journalist working for Shoyu News. He was writing a story about the author Soseki Natsume at the time of Jezaille Brett's murder.

Menimemo was the criminal of Jezaille Brett's murder. Accepting his guilt, Menimemo lamented the events of the past nine months. Susato Mikotoba later visited Menimemo at the detention center before embarking on her journey back to England.

He told that her that the body of Kazuma Asogi, an exchange student who was meant to go to England but had been apparently killed during the voyage, had never been recovered; it was supposed to be handed over to the Japanese embassy in Hong Kong, but had mysteriously disappeared.
