As captain of the royal guard, Mahado commanded the soldiers at the tomb. [[Siamun Muran (manga)|Siamun Muran]] stressed the importance of setting new traps, rather than repairing the old ones and Mahado affirmed that there was a new trap sure to stop any thief. Seto was not totally convinced suggested that Mahado not be given another chance and be stripped of his priesthood the next time the tomb got robbed. Siamun reminded Seto that was the pharaoh's decision to make. [[Dark Yugi (manga)|Pharaoh Atem]] then advised Mahado to not be blinded by his guilt and to focus on fulfilling his duties.<ref name="mw d 14">{{chapter|Yu-Gi-Oh! Millennium World|14|ref}}</ref>

Mahado asked Siamun about ''ka''<nowiki>'</nowiki>s strength growing with the hatred of their host. Siamun replied that it was not just hatred but the strength of their heart. In place of hatred, Mahado believed himself to have enough devotion to the pharaoh to strengthen his ''ka''. Because the pharaoh forgave him for his failure, he was willing to stake his life for his duty.<ref name="mw d 14" /> [[Mana (manga)|Mana]] scolded Siamun for saying Mahado's spirit was weak and claimed that he had incredible magic that he has not used since the day he first put on the [[Millennium Ring]].<ref name="mw d 14" />

While ===Battle===Bakura summoned [[Diabound (manga)|Diabound]], who having fed on his hatred, had grown stronger since [[Priests, Atem and Bakura ridiculed Mahado's powerpalace Diaha (manga)|their last ''Diaha'']].<ref name="mw d 14" /> With no fear of innocent bystanders being hurt, while he was in the tomb, Mahado claimed was able to refocus his powers from suppressing the evil of the Millennium Ring to have been holding back strengthening his power before''ka''.

It dodged the Millennium Ring at bayattack and while Mahado chanted a spell, struck Diabound with its "Magic Blast" attack. But inside Mahado then transferred his ''heka'' to the tombmagus, allowing it to attack again with its "Magic Bullets". The attack had some impact on Diabound, he could freely unleash who then disappeared with its wall-phasing ability.<ref name="mw d 15">{{chapter|Yu-Gi-Oh! Millennium World|15|ref}}</ref> Bakura commended Mahado on being able to use his ''heka'' to double his full ''ka''<nowiki>'</nowiki>s powerand deduced that he must be a spirit sorcerer. Just like a wizard has ways of fighting, without fear Bakura said that a thief also has ways of hurting innocent bystandersfighting, as he deliberately triggered a trap, causing giant axes to swing like pendulums over the bridge. While Mahado took care to dodge the axes, Bakura climbed up on one and laughed at the irony in him being able to use the traps set for thieves to his advantage.<ref name="mw d 1415" />
