Yuuma was inside her lab working on her inventions again. She has been in here for the last twelve hours since Han left and she hasn't had a single wink of sleep since then. The amount of work that she has to do now was immense and she knew that she was almost out of time before the fight begins.
Han will finish the temple soon and I might not be done by the time he comes to take the army to the celestial plane! I don't want to disappoint Han after telling him I was going to help him.
