An Explosion on This Wonderful World! Not intending to hand Chomusuke over, Megumin comes up with a plan to use a stuffed cat toy to lure Host into a trap so she can use her explosion magic on him. During the night though, Yunyun sneaks into Megumin's room and steals the cat toy. Believing Megumin is still asleep, Yunyun admits that she's grown to respect Megumin and her choice to learn explosion magic, but she knows that Megumin's plan won't work. Instead, she has recruited a party to help fight Host, and she casts a sleep spell on Megumin to prevent her from interfering. Megumin wakes up the next day and chases after Yunyun, receiving a blessing from Cecily on the way. Meanwhile, Host neutralizes most of Yunyun's party, but she is able to cast a paralyze spell on Host but accidentally paralyzes herself as well. Megumin then arrives and casts her explosion on Host, destroying him. Afterwards, Cecily leaves on a journey to gain enough levels so she can eventually take over Axel's local church. Yunyun, realizing she won't be able to improve herself by relying Megumin, also leaves on her own journey to learn advanced magic and briefly crosses paths with Megumin's master. Despite Megumin defeating Host, adventurer parties still avoid her. With little other choice, Megumin answers a party recruitment ad and meets Kazuma and Aqua for the first time.
