Mori no Hotori de Jam wo Niru: Isekai de Hajimeru Inakagurashi

Margaret's life is cut short when she gets into a fatal accident at her workplace, except instead of the afterlife, she finds herself in another world! She's rescued from the brink of death by an elderly retired noblewoman who lets Margaret live at her mansion. What awaits her there is a stark contrast to her previous life: relaxed and laid-back countryside living! Sure, there's the whole fact that she was summoned to this world as a special being known as a Spirit Caller, but she couldn't care less as long as she gets to eat delicious food! She's going to get a fresh start taking life slow in this new world filled with magic and spirits!
