A lot of research went into these due to 18TRIPs tendency to mix up words, use Gen-Z slang that hasn’t been picked up by everyone yet (or limited to TikTok) and make up their own words (“Omotenashisto” -> “Hospitalister”). I used dictionaries, searched forum results, looked up how people use these words on social media, went TikTok digging, etc.

I tried my best to localize in a way that should make sense even without added context. I only explained the ones that I thought might needed some more back-up in a cultural sense or because it was a specific JPN thing. Thus, not everything has been explained. However, I hope things are clearer compared to the first version that was posted. For Renga & Yukikaze: For ぽゆぽゆ (poyupoyu) there is no definition or anything for this word, but from context clues and digging through how people used it, I deduced that it means something soft and squishy like a plushie or cheeks, so to say. For Renga & Liguang: かりそめの宿縁 (karisome no shukuen) is a Japanese saying about a fated connection of bond that only lasts for a brief moment, but leaves a deep impact on your life. For Renga & Raito: Party is mispelled in the katakana as “paachii” and not the usual “paatii”. Renga has a tendecy to say English words wrong. While “friends” is spelled the correct way, both words have been “mispelled” to drive the point home. For Renga & Kinari: なぁぜなぁぜ (naaze, naaze) is JPN Gen-Z slang from Tiktok. It’s a statement made as an act for complaining, with a bit of sarcasm and irony thrown in at times. Like, “I said I wanna diet but I ate a big meal anyway! なぁぜなぁぜ” or “I’m an idol but I get more anxious doing improv than performances! なぁぜなぁぜ”. Best way I can describe the usage in this context is Renga is throwing a bit of a self-aware tantrum as to why Kinari would correct him. (As mentioned earlier, he isn’t good at English). I guessed a close equivalent would be “nuh-uh”, since that is a dismissal of someone else’s opinion without actual good reason, even if the other person has a point. For Renga & Netaro: まんまん (manman) means “a lot” but I also believe it’s a reference to meatbuns (nikuman). For Kafka & Yodaka: Hanbei is Takenaka Shigeharu, a Japanese samurai from the Sengoku era. He was known for being Toyotomi Hideyoshi’s strategist. For Liguang & Yodaka: 闘牌伝 (touhaiden) is related to Mahjong stuff. 闘牌伝 seems to be an old timey Mahjong video game with RPG elements. Rekka is a fighting game term, and I will quote the website The Fighting Game Glossary by Infil on this: “A type of special move that has multiple stages, as long as you input more commands to continue the sequence. Not all multi-part specials can be called rekkas though; a rekka tends to have exactly three distinct parts and will move your character forward along the ground with each new input.”  For Akuta & Nanaki: They went to the same kindergarten and were grouped together in the “Oden Class”. Japanese kindergartens, from my understanding from researching, tend to have a name for their class, rather than a number. To give an idea what such names could be, in 2019 the website hyenasclubs hosted a poll of most commonly used names for classes, and the top 3 were “baby chick” (hiyoko), “peach” (momo) and “dandelion” (tanpopo). For Akuta & Muneuji: My take on はっけよい輝矢部屋 (hakkeyoi kaguya heya) is a bit of an elaborate bit joking with Princess Kaguya of the Moon (from Tale of the Bamboo Cutter) because I was wondering why they suddenly opted for Muneuji’s last name instead of first. (I might’ve also just overestimated Kaguya Heya being some joke on Kaguya Hime). Hakkeyoi is what a referee shouts at the start of a sumo wrestling match. For Akuta & Ushio: I think ポジティブに腕押し (positive ni ude oshi) is a take on 暖簾に腕押し (noren ni ude oshi) that means something has no effect or is pointless. Lit. it means “pushing a curtain with one's arm”.    For Akuta & Tao: Akuta Nine is a joke on the baseball movie Gyakkyo Nine which is an adaptation of the manga of the same series, I believe. The movie is referred to as GK9, hence I made it AKT9.  For Akuta & Ryui: The original is OYAxKOBU which comes from 親分子分 (oyabunkobun) meaning “boss and his underlings”. Akuta also calls Ryui by “Oyabun”.
