for some time now, all the members of Wonderland x Showtime have noticed that Miku, Kaito, Meiko and the rest of Vocaloid have started to become very... protective. And everyone knows that the entire SEKAI group is created from Tsukasa's feelings.. So Emu, Nene and Rui began to wonder what could be the reason for the sudden change in SEKAI.

they had a lot of suggestions, but none of them were right. every time they asked Tsukasa what was going on, he replied that he had no idea.

however, after one visit to SEKAI by Rui and Tsukasa, the guys could hear the cry of... a baby?! there's no way.. they thought Len or Rin were the cause of the crying, but they were wrong.

it turned out that feelings from the SEKAI created an new emotion...? As crazy as it may sound, it was true. It was a little boy who had hair the same colors as Tsukasa! he looked like his child, but he wasn't. when Tsukasa started to gently touch the kid's hair, he saw that underneath the blonde color there was still a purple color, the same as Rui's!

"Tsukasa-kun?" Rui asked, seeing Tsukasa starting to blush like crazy. Rui had no idea why, but Tsukasa realized that it was most likely because of his feelings he had for Rui.

"what happend? here, let me see."
