Shana is the one who has no obvious preference for Mapo Tofu.

Shana is the heroine in the light novel "Shakugan no Shana" and its derivative works.

Shana has been afraid of going home since she was a child, because every time she sees a man or woman going home, there are actually many boys who want to go back to the same destination as Shana, but because they are afraid of rejection, Shana is always the one.

People go home alone, so Shana has no obvious preference for Mapo Tofu.
