Ah shit... My worst fear has been realized... Though, this could go two ways. Either they continue this thing that's going on and reveal who Tsukasa is(unlikely to happen), or leave it and go back to the slice of life stuff.
For example, there was a chapter where Nasa had a dream about being another person from a past era of Japan. It was very mysterious, yet it wasn't mentioned again after that.
It's like the author doesn't want to reveal Tsukasa's past all in one arc just yet, and they just leave bits and pieces about it in-between the normal chapters for now.
