Plot
The DX Brigade is in deep trouble when they heard that their usual porno store changed it's clerk. From a dilly-dally old man to a naggy middle-aged guy lecturing high school students about pornography. They then decided to dress up as a typical office employee to make the clerk believe they're not high school students. Unfortunately, the clerk didn't fall for it and even tries to call their school until an old man claimed he asked them to buy those magazines. The old man introduced himself as "Yama-chan", a homeless bum who loves to drink and smoke. He starts grading their magazines and as time passed,they got chummy with him and talked about meaningless things.

Aoshima's time slip activated, he does the usual things (look for Wagatsuma's panties and etc.) until he questions himself for what is he doing for a living. Scared if being like Yama, he searches for clues that might help him know his occupation. He then finds a suspicious bad that maybe related to his work. He checks what's inside and sees a fan and a hankerchief. He concludes that he might be a comedian (comedians in japan use those as props) and starts practicising his routine. His phone rang and Wagatsuma wanted to meet up and have dinner with him. While looking for a place to eat, he sees a very weak old man who's somewhat familiar to him. Wagatsuma tries to aid the old man and thanked her but told her he's okay. Aoshima is still thinking who he was till he sees the old man wore his hat that's similar to Yama-chan's. They then took him to a hospital to check him up. After the tests, the doctor's issued Yama a death notice and told him that he has a cancer in it's last stage. He only has a year and half to live. He said it's too late to change things. With the help of his powers, Aoshima decided to change his future.
