Sasaki and Peeps, Vol. 3 (light novel) (Psychic Battles, Magical Girls, and Death Games Can't Contend with Otherworldly Fantasy ~Or So I Thought, but Now a Storm Is Brewing~)

As always, Sasaki and his pet bird (and otherworld sage) Peeps continue to leap across worlds, trading goods for a profit. Thanks to a little help from Futarishizuka, they've found a way to exchange otherworld valuables for modern currency, and Sasaki has been studying up on magic, making him unstoppable against psychics and magical girls. All that's left is to make as much money as they can, retire, and start relaxing—but that won't be so easy. In Peeps' world, the dispute over succession begins in earnest, and back home, the psychic battles never stop. Not to mention Sasaki's neighbor, who is caught up in an angels-vs-demons death game. As worlds collide, Sasaki’s in for even more chaos!
