It took a while for us to learn her full first name is Riri, but I didn't expect a reveal this far in for Tatsu-nii either. So he's Tatsumi. Tatsumi Ashihara. I didn't really expect this because Tatsu is already a fairly common first name for a boy, but "Ri" is not for a girl.
Our cinnamon roll gave herself an edgy makeover and a bad habit along the way, but it turns out much of the same sweetheart she used to be still remains beneath. Good girl asking mom about it. Gap moe going strong this chapter.
I love how mom still cares for her daughter to at least ask if the man she loves can be trusted and not just "Is that so? Do what you want". I'd like to see her and Tatsu-nii have a talk before he takes Ri-chan away to live with him though. I don't remember seeing the two of them interact before, at least in any meaningful capacity.
