Lucy's manga / #supernatural(95)

Honestly lost track of what was going on when they went on the train, the beginning was good and all but around chap 30 the mc started to seem a bit too stupid and like the annoying hero mc. I dont really get who the guy with old occult club was, like was he a student with Sumio and shi or was he students with the parents like huh??? I still have no clue why Kirio and Sumio were Enigma and why Kirios dad had a vault thing on his head, And whats up with that weird ending like??" Omg everything verry good now but uh oh no memory!!! I, Kirio the bff of Sumio will get memories back of everyone! Everyone: Yes!! friendship sumio our savior! Goes to sumio... Sumio is acting goofy asf on stage like boy wtf?? wym a ghost of yourself??? did the girl childhood friend like Kirio or Sumio?? literally couldve been good but the end is just sucky..
