Tachikawa Squad

"Alright, listen. I'm gonna say something good. Look at our emblem. There are three swords, right? This first one is me, the second one represents Izumi, and the last one is... My second sword. In other words, you're still a novice, so no getting puffed up. [...] Kunichika, you're the crescent moon on the back."

- Kei Tachikawa to Takeru Yuiga
