[First, sorry for bad english]
I discovered on a French website that Dasoku is Aoi and Ririri's father (both are odorite)
"Famille : 3 enfants (un garçon nommé Aoi, une fille nommé Ririri et une petite fille)"
"Family : 3 childrens ( a boy called Aoi, a girl called Ririri and a girl)"
Then, on the comment, I saw :
"Ahaha, c'est moi qui as rajouter ces informations grace à sa fille parce que je lui ai dit "Dasoku is your father" et elle a dit "Yes !" [...]"
"Ahahah,it is I who have to add informations through his daughter, I asked her : "Dasoku is your father" and she said : "Yes !" [...]
(the girl/boy say that she/he/ met Ririri in real life)
Idk if it's true or not, I just wanted to share with you these informations. Now I'm so confused.. ._.
