A collaboration event between the anime “Bungo Stray Dogs”—based on the popular manga by Kafka Asagiri and Haruka 35—and Yokohama’s Hakkeijima Sea Paradise will be held from October 1 to November 9, 2026. Newly drawn mini-character illustrations featuring the characters spending time with marine creatures, as well as newly drawn illustrations evoking an aquarium date, have been unveiled.
