The next episode titled "An Invite to a Meeting ~Simply Put, I Just Want to be Popular~" of "Mob Psycho 100" Season 1 will pick up from where the second episode ended, with Mob finally realising what he wants to do with his life.
Watch the next episode of "Mob Psycho 100" on Crunchyroll.
In Episode 2, Mob, who is mostly a socially awkward guy, discovers that in order to impress his long-time crush Tsubomi, he needed to be popular and he decided to join a gym for enhancing his personality.
Once Mob realised that having psychic powers won't help him win Tsubomi, he joined the Body Improvement Club to rather focus on his physical fitness. In the next episode, Mob will be seen surviving the first day of his training at the club, even though he will find it hard to work-out even for five minutes as he is not the athletic type.
Given that if the anime series follows the plot of manga, the Telepathy Club leader will advise him to use his psychic powers to find out what girls usually think of and Mob will eventually try it out.
Unfortunately, the first few attempts won't work for Mob and he will be left confused and disheartened. Hence, he will seek help from his friend Reigen, but even Reigen doesn't have much experience with the girls. The confusion will leave Mob frustrated, causing his psychic powers to rise significantly.
There is a significant possibility that Mob will be seen in his full potential in one of the upcoming episodes, after rendezvousing with a disgusting person named Lord Dimple.
