They’re playing a hints game. For example, if the word to guess is “lion”, you’d give hints like “animal, king, gold”.
[6] Kuroko!? Kaito (Kageyama): Alright, let’s announce the hints. Saitou Souma-san, please! Souma (Yamaguchi): Micchi. Kaito: Mi..? Souma: You’ll understand once you hear the other hints. Kaito: Alright. Ok, next up is Uchiyama-san. Please! Ucchi (Tsukki): Height. Ayu (Hinata): Aaah, I see. Kaito: And Murase-san? Ayu: Orange. Souma: Eeeh!? It’ll be hard to guess! Ayu: That’s— Kaito: Orange? Ayu: Orange. Souma: K-Kaito-kun, good luck! Ucchi: Well, Kaito-kun, on three— Kaito: Wait a sec! Ayu: Your answer! Kaito: Already!? Seriously!? Ucchi: Kaito-kun, your answer is..? Kaito: …Oikawa Micchi? Ucchi: WRONG! Kaito: Uchiyama-san sounded really happy just now! Ucchi: Wrong! Ayu: He looks happy! Ucchi: It’s not Oikawa Mitsuhiro-san! Souma: It’s not the prince! Ucchi: Let’s check the answer. Ayu: Yeah. Ucchi: I think my hint was the most legit. Ayu/Souma: That’s true. Ucchi: Announce the answer. Ayu: The right answer is… basketball. Kaito: ??? Ucchi: Why did you say Micchi? Souma: Don’t you know Mitsui Hisashi? [T/N: SLAM DUNK character] Ucchi: I do, but… I tried not to overlap with anyone. You need height to play. Ayu: I also tried not to overlap. Ucchi: Why orange?! Souma: It’s too vague. Kaito: There’s no way I’d guess correctly! Ayu: It’s the color of basketball, right? I thought someone would say ball. Kaito: At least write misdirection or something! [T/N: Kuroko no Basket reference] [laughter] Kaito: Shueisha! [T/N: Weekly Shounen Jump’s publisher] Ucchi: The first thing that came to my mind was Kuroko. [laughter] Ucchi: But that’d be bad to use in more ways than one. Souma: Kuroko has the same publisher [as Haikyuu!!] though, so— Kaito: —it’d be OK.
