Blender's viewport shaders won't have all the toon shading features to match koikatu in game; well maybe evee in 2.8 does but it won't transfer to unity or in-game anyway. Just use blender to make sure the UVs line up, then you can take an existing unity toon shader (silent, utsv2, xiexie are good bets), and try to match up the textures as best you can in unity.
