Debo Tanabanta (デーボ・タナバンタ Dēbo Tanabanta) is a vain and wily Debo Monster themed after Tanabata and armed with the Bamboo Forest Spear (竹林槍（チクリンやり） Chikurin Yari), created to serve Joyful Knight Candelilla by granting Tanabata wishes that are written on his special paperslips on July 7th. However, once those wishes are granted, they will drain the joy energy out from the victims, and by the dawn of the 8th, all who had written on Tanabanta's slips of paper would die.
