>tell them apart

Why would you need to when they are all essentially the same character bar Aoko?

Who's the one in all black?

>>121187293
Aoko has brown hair, one's a loli and the other two are shit.

>>121187293
You don't.

They are all shit. Especially the first one.

>>121187293
Aoko and Mana are fine. The two on the left are shit.

Not sure what Mana has similar to the other 3. She's not even tsundere. Also Mana is best among those.

>Nasu is a good author

By their anus.

Obviously through those completely unique and well written character personality, which are commonly found in media such as Anime or Manga or VN.

OP sure is a racist

By clothes, hairstyles and mannerisms.

>>121187293
Mana is a loli that loves bomber-kun, Aoko is super tsun, Rin has a lewd anus, and Azaka is ultra dere when it comes to her brother.

Their eyes, facial structure, hairstyle, style of clothing.
