The teaser site for Isekai Quartet, a new crossover anime featuring the puchi-chara version characters from the four recent popular isekai (another world)-themed anime series, has posted a 60-second first teaser introducing the main characters from Overlord, in addition to Rem and Ram from Re:Zero − Starting Life in Another World in the end.
The four series are: Overlord, KonoSuba: God's Blessing on this Wonderful World!, Re:Zero − Starting Life in Another World, and The Saga of Tanya the Evil. More characters from other series are expected to be introduced in the forthcoming PVs in a relay format (Like Rem and Ram, some of the next series' characters make a brief appearance in the end of the clip).
The special crossover anime is set to premiere in Japan in the spring of 2019. Its plot is introduced as: "One day, a mysterious button suddenly appears. By pushing it, they are transported to another
different world!! The characters from another worlds gather there, too...!?"
