Ding, you have been selected and invited by the Tiantian dimension chat group, do you want to join?

No, no, I’m already at level 6, so I just came to the chat group.

The beautiful monster princess: Although I lost a good chicken, the monster girl is really good.

Dagu is not Dagu: As a partner of justice, it is our duty to maintain the peace of the universe.

I’m your father: Kulala, I’ll show you a hand-torn black beard to cheer you up.

Bai Feng: This chat group is a bit indecent.

Kurokawa Risa is an ordinary office worker, who has practiced lots of cooking while living alone. One day, she wakes up in another world, with a concerned little spirit hovering over her! She has apparently been transported to a magical, spirit-filled realm by the will of the goddess, and there is no known way for her to go back. She is taken in by a wealthy couple, and they and her new spirit helper treat her with nothing but kindness. There is one problem, however–the food in this magical world is gross! Risa insists on helping the household cooking staff prepare a traditional meal from her world, and it is a big hit with her hosts. Soon Risa knows what she should do in this new world; she should open a cafe and treat everyone to delicious food!

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.
