Poor Louise. Summoning angered Vegeta in the summoning ritual, and then Vegeta killed her.

Louise Valierre had long been a fan of the Dragon Ball series, and had even made it her mission to learn the ancient ritual of summoning the powerful characters from the series. After months of studying and practice, she finally succeeded in summoning the powerful Vegeta in the ritual. The ritual worked, and the Saiyan prince appeared before Louise. But his arrival was not a peaceful one. Vegeta was angered by being called forth, and flew into a rage. Despite Louise's pleas and attempts to calm him, Vegeta lashed out with his ultimate power. His devastating energy wave destroyed the ritual chamber, and with it Louise. The powerful prince had vanquished Louise with a single attack. Even if she had trained and gained extreme power of her own, she was no match for the mighty Vegeta. Her ambition had cost her her life.
