The Game Master Has Logged In to Another World: Volume 4 by Akatsuki

Masaki and his friends depart for the Beastmen Kingdom to help Levia search for Jörmungandr—one of the Three Dragons—whose presence has become faint in recent times. The party takes a shortcut through a Fairy Path, but a powerful magic storm catches them by surprise, flinging Masaki, Akiha, and Levia far off course. Finding themselves lost in a gigantic forest, they soon realize that the magic storm has disrupted the flow of mana, leaving them unable to use magic or contact their companions. Thankfully, the game master and his two comrades meet an unexpected guide: Alice, a fairy. Will they be able to overcome the perils of the forest and the magic storm’s disruption to reunite with Adel, Youko, and Nemea and uncover the truth about Jörmungandr?
