I think this is a good ending, still feels rushed but I am glad we got it.
I think the message of individuality is actually handled well and it didn't make the main character greedy for accepting it over world peace, like a lot of other stories do.
I have been wondering where the Tora sister has been? Just chilling in Kiryuin's pocket the whole time?
I wonder if the plot of finding her sister that was set up earlier but not really explored is going to be resolved.
