[This is the closest I could get with the app so I’ll put anotations on their looks like this]

SHEILA KUNO (Japanes-ish adaptation of her surname)

Sheila was an Indian exchange student at the sextuplets’ school. She was quite popular, participated in the drama club and was great at acting. She absolutely loved (and still loves) Japan and studied Japanese back at home, yet her pronunciation wasn’t the best at the time and she had to say some words in English. She had to go back after the year finished.

She was childrish and out-going, a romantic that went stright to cheesy whenever Karamatsu was around. She was a close friend to him, even with the obvious crush between them.

DAYOKO (without surname)

[Ignore the uniform]

At the Dayon Tribe, they have the tradition to make a journey when after their 18th birthday. During it, Dayoko fell on the river and appered in the outter world where after a while she adapted (that’s why her face looks "normal"). She learnt so much things but her journey was cut short when she treated to help Dayon and somehow got back to the tribe. 

She was quite curious about that new world and overly kind to everyone. Luckily, whenever someone tried to trick her there was another person willing to help her. Thanks to this journey she knew how to help Choromatsu when they met.

AURI FUJIOKA

[Her hair is write and her eyes pale blue. That’s not her school’s uniform]

She lived in a neighbourhood nearby the sextuplets’ but not close enough to go to the same school. They called her Shiroko-chan mostly as an insult and was often target of pranks. She got used to it and it lost its effect, she often tought they were idiots for enjoying something like that. She used to spent the breaks going to play and take care of her cat’s kittens (on Iro’s "about" page) at the building place they were to give them for adoption. 

She was a calm girl and had the mindset that life is too short to worry for stuff. Her younger brother saw Ichimatsu as his big brother and he was the one that kinda made them start thinking about each other as more than friends.

ANOKO DOROBOU

[Again wrong uniform and WHERE ARE YOUR FRECKLES GIRL?!]

She went to the same school as Auri and considered her her only true friend since the others were fake and she knew it but kept going with them because she didn’t want to be alone. She was in the baseball club and that’s how Auri started calling her Homerun girl which then turned into Homura. They called her Shinitai-chan for a misunderstanding but it didn’t last.

She acted like her friends expected from her to please them and blamed her sister for not letting her be closer to Auri. When she didn’t have to pretend she was really bitter because of her situation.

KANOJO DOROBOU

[Wrong uniform, freckles and her hairstyle is a bit different]

Kano is a tomboy, not just to differenciate her from her sister but also to be more intimidating and keep bad persons away from her, sometimes getting violent. This is why they called her Kano-kun and she liked it. She didn’t want Anoko close to Auri to avoid people mocking her for going around with a weirdo.
