Garo: Makai Senki Episode 6

After a brief sparring match with Kouga, Rei investigates a Horror tree. In flashback we are told of the tree's owners, a husband and wife who invite people into the house to view the tree's unique shape when viewed from their house and to eat a snack of tea and their home grown vegetables. However, this is shown to be a trap where the guests are each poisoned and then buried under the tree, who rewards them in turn by letting them have dinner with a projection of their dead son.
