Goddesses' Whim!!

You, the protagonist of all this, with a big heart (and something else..)
Because of your past, you are someone with a boring and lonely life who does nothing but study and train.
But one day, given your personality to help others no matter what, you decide to give your life to save another, which attracts the attention of a certain Goddess.

Now, with the opportunity to return to live in another world, you will not let everything be as it was before.
