4

While on their way to school, Hachiman and his sister Komachi Hikkigaya discuss the car accident he was involved in on what was supposed to be his fist day of high school. Afterwards Shizuka reprimands Hachiman for his choice of future occupation and reminds him about picking a three-person group for the upcoming workplace field-trip. Later the Service Club receive a mysterious shared text message. Hayato then requests that the Service Club put a stop to the message which paints his clique members Kakeru, Yamato and Oka as delinquents. The Service Club then links the message to the field-trip and deduce that one of the three plans to eliminate another so they can form a group with Hayato. Hachiman and Yui then take turns gathering information, however Yui ends up failing miserably due to her inability to remain subtle. Afterwards, Hachiman begins observing Hayato's clique until Saika interrupts him. However he solves the mystery when Hayato joins their conversation. Hachiman later explains the cohesive relationship between Kakeru, Yamato and Oka, and has Hayato take himself out of their group to give them a chance to bond. Hayato then thanks Hachiman by grouping with him and Saika for the field-trip. (Source: Wikipedia)
