Seita will grow up to be an amazing shipper on the internet someday. Also from this point forward, since I can never remember if the e comes before or after the i, I will call him "ζ" (lowercase greek symbol for Zeta). Zeta, because it's close to his name, and lowercase because he's a little kid. (Also Uppercase Zeta is literally just a Z.)
I also just thought of one for Junta, "ι". (The symbol for Iota) Iota, because it also means a very small (or insignificant) amount of something. Insignificant enough to not be noticed by most.
