I knew it!! Kou was going to find closure for M1tsuba, so now he can focus more on helping Mit2uba. But... ow...... does this imply that Mitsuba never took a picture of his mom? And that the only important person he photographed is Kou? That hits even harder. He couldn’t even do it in life. That happened in death.
I have a feeling that closure from the dead will be a huge theme near the end of the manga. Those who are alive are doing their best to help supernaturals feel content, and hopefully stay away from the near shore. But those supernaturals are persistent..... man it is WAY too late for my brain to be working properly, baha
