Because he is hallucinating look at panels carefully nanjo's clothes changed from tank top to a shirt

Honestly after reading through multiple comments I feel we will know in next chapter. Some of the things which others said made sense sometimes but at the same time it felt everyone is assuming a lot. So I will wait for the next chapter.
Is there a reason Nanjo is standing on a skateboard? It was just so bizarre （￣へ￣）
