(spoiler) We lack Lu Xiaotang screen time

I loved Lu's silly and how she makes the story lighter in a way, but farther in the manga she basically just disappears, she just happens to be defending and tending to the store and does not appear much after the "escaped criminals" arc (forgot the name). PEOPLE, WHAT DO YOU THINK? AND WHAT ELSE WILL SHE DO AND WHAT ELSE WILL BE HER IMPACT IN THE STORY??
