That was also the same day Shido encountered Tohka and later discovered the real reason behind the spacequake incidents.
The next time Tohka encountered Shido, she was again under attack by the AST.
During their third encounter in which they went out on a date, Tohka and Shido established a bond, as the boy explained to the Spirit that not all humans were like the AST who are out to kill her.
Tohka was later captured by DEM at the end of Miku Lily.
When Tohka first appeared on Earth, on the 10th of April, she came under attack by the AST.
