The Fifth Martial God, Xiang Shan, who was active on Mars approximately one hundred and thirty years ago, was ostensibly a lone hero, but in reality, he was connecting potential chivalrous elements within the Scientific Knight Order, attempting to establish a complete anti-Protector organization.
Around the time of the siege of the Sixth Martial God, the government announced that the Fifth Martial God had been killed.
Latter-day heroes occasionally use the case of the Fifth Martial God to educate the younger generation, reminding them that fighting alone is inadvisable.
"Only now do I understand why I failed back then..." Reflecting bitterly, Xiang Shan said after regaining his freedom from the Lonely Prison Knight Order, "It turns out this niche was already full."
