Just after this chapter, I realised something.
1. The time traveller was from the future trying to defeat the Buddhas. That's Zi-O reference
2. He and the gang took refuge in a clockwork. Sougo is a son of a clockworker who stays in a clockwork. That's another Zi-O reference.
3. The item he used to defeat the Buddhas is called Genius. Genius is Build's final form
4. Bruh there's even Ichigo pose here
