Astra was looking outside the window when she felt a weight on her shoulder.
She looked to her side and saw Kaito sleeping, opposite them were Takao and Kaname.
Kanam'e head was hitting the window while Takao's was falling. From all the crying that they did, all three were too exhausted that they have fallen asleep.
They were already on a train on their way to where their family lives.
Astra waved her hand and somehow the cubicle they were in became even more silent. And an invisible force is supporting Kaname and Takao in order for them to sleep much more comfortably.
When they were about to depart a while ago, Hayate asked her to have some time to talk with them regarding what really happened on the artificial island but she had declined saying they already said everything that has to be said.
At the same time, the real reason is because she only has so little time right now. A few days and this body would die.
