Yuta Tsuda is a high school student who suffers from a mobile phone addiction. He panics and suffers withdrawal when he is not on his phone. When he gets his phone confiscated in class, he goes home instantly and asks his mom to get a new one. Irabu starts to text him on his phone after getting one himself. Yuta asks Mayumi for her phone number, but she doesn't have one because she has no friends. After turning up to a Christmas party, Yuta starts to realize that his friends take advantage of him and make fun of him for his mobile addiction. Yuta subsequently starts removing all his contacts out of his SIM card, when Irabu and Mayumi call from the hospital and invite him to a Christmas party at Irabu's office. In this episode, Irabu mostly appears as his 'big' form and shortly changes to his 'little' form. This is the only episode so far where Irabu doesn't appear in his feminine 'middle' form. After the vitamin shot, Yuta turns into a pale blue woodpecker with different colored spots.
