She is actually EbilFish's personal slave driver.
Whenever he's about to fall asleep instead of working,
she leaves her post at the city and gets out her whip.
Perhaps she goes to the developers' rooms instead.
"I'm sick and tired of complaints. Before we lose the knights, hurry up and do something."
She then kindly buffs them with ATK speed+ and [thought process] casting buffs.
Their [update in Progress] bars become unstuck and start to increase.
If an error exists, the Almighty Lena takes out her whip and destroys the evil error presence.
Realizing her further stay may distract their male instincts and hinder their progress (she sips coffee and chats with the female workers to increase their enthusiasm and motivation),
She then takes her leave to go buff the knights again
Only to be forced to go and whip the developers back into shape yet again at a later time.
So Knights, Do not hate on the Great Lady Lena if she is missing from her post,
for she is doing us all a grand favor and whipping the devs into shape.
