Terao is a struggling office worker, having worked at the same place and postion for all his life. He has a young daughter and lives with his wife and mother-in-law. He seems shy and polite, often trying to please people but always making things worse in the end. An example being when he tried making Mika happy by buying her a gift, which turned out to be a mess.
Throughout "Vomiting Point", he was told by his younger superior that he needs to improve and make more sales in order to keep his job. After drinking a whole tower of beer, he created a ghost out of vomit, who Panty and Stocking proceeded to kill. After meeting the angels, he asked them to come home with him in order for his daughter to meet them, but was turned down and given their autographs instead.
