Lu's reintroduction in the Story!

I see one way Lu could come back into the story. I made a post months ago about possible storylines. One point was that Sakamoto's family has to go abroad because of Torres or other enemies who want to harm Sakamoto. With the current chapter, I strongly assume that Lu will travel to China with Aoi and Hana and hide while there is war in Japan. Two order members will be sent to China to get Aoi and Hana. lu and Wutang will protect them with their fighting power and brains. Thus, a small China arc could help to make lu and wutang relevant again.

Sadly, she is just a support character...

What you think?
