I also love how different they are in personality too, Ortho is very cheerful & extroverted while Idia is a gloomy shut-in
Ortho is also very curious and Idia prefers things to be simple
Ortho tries to see the good in life while Idia always looks at the bad
sun and moon or smth
something I love about the Shroud bros is how different they are in appearance
side from the obvious height difference, Idia's pupils are very small while Ortho's pupils are big enough to almost cover the whole eye
also, Idia has super long hair while Ortho's hair is very short
