What is going on currently??

I've read this somewhat around till ch 200 to 220 of I'm not wrong. The last I remember reading was that online scam sales. Kinda got busy irl and wasn't able catch up till now. And this recently showed up on YouTube shorts so I kinda was checking it out and it was just plain fights with more and more characters. So help me out here. What exactly went down? Do we get anything about the mystery of the 2 bodies? Why is there so much fighting? Are they even still going to school or what? Did it go somewhere far from the original story ?
