The HXEROS headquarters generously grant Retto and the team a vacation at the beach, but when they arrive, they discover that the beach is covered with suspicious-looking sea cucumbers. Discouraged at the prospect of not being able to go swimming, the team head back to the hotel where they run into the Tokyo Branch, who have arrived to exterminate the sea cucumbers, and end up helping them in the extermination. Toma Taiga, the only male member of the Tokyo Branch, asks Retto to be his mentor. Toma says he admires Retto, but what secret is he hiding?
Yeah, but you didn't tell me
how you're gonna do it.
Trotzdem hast du mir überhaupt
nicht gesagt, wie du sie anstaust.
Sí, pero no me dijiste cómo lo harías.
Je sais, mais comme
t’as refusé de m’expliquer…
Sim, mas você não me
disse como vai fazer isso.
