Respider (レスパイダー Resupaidā?, 43-44, 13 Riders): It is a Jorō Spider monster. It appeared among the Mirror Monsters that helped to protect Yui. A Respider appeared in the "13 Riders" special, where it came to Mispider's aid in fighting the previous Ryuki before he gave his Vent to Shinji. That Respider was destroyed by Ryuki's Drag Saber. Another appeared to aid another Mispider and a third Solospider, but both were killed by the Riders during each fight.
