History:
(Demon Days: X-Men#1 (fb) - BTS) - Once
upon a time, humans and Yokai (spirits of earth, air, fire, water, life
and death) lived in peace. The mountain-dwelling,
massive
ogres known as Oni co-existed with humanity who dwelled in the
villages. However, when the humans expanded their territory, cutting
down forests and digging into the mountains, the Oni saw their lands
vanished. Starving, the Oni raided the human villages for food; not
appreciating that they had caused this, the humans considered the Oni
to be marauding monsters and began to fight back.
(Demon Days: X-Men#1) - To feed
himself and his starving son, the Oni Hulkmaru raided a nearby village.
Hearing him, the local Tsuki confronted Hulkmaru with bow and arrow,
and although her tiny arrows were harmless to him, Hulkmaru fled.
(Demon Days: X-Men#1 - BTS) -
In exchange for a bed, the traveling mercenary Sai (along with her pet
wolf, Logan) offered her sword in the village's service. Upon hearing
of the raidings, Sai shared her experience that the Oni were wary but
not aggressive and did not attack unless given a reason.
Any further discussion was
interrupted when a villager rushed in and announced that Orichi, the
serpentine creature also known as Venom, had returned, devouring two
villagers and reclaiming a local temple. 
The locals sought the aid of Juju, a jushi (sorceress who mixed magic and medicine), who noted how Orichi was beginning to bother her for coming right back after she kicked it out. She suggested that they ally with the Oni for a more permanent solution.
Although some villagers objected, calling the Oni barbarians and monsters, Sai told them that she would deal with the Oni. Meanwhile, Juju gave Tsuki incendiary devices ("fireworks") to place around the temple Orichi was inhabiting.
(Demon Days: X-Men#1) -
Appreciating as Sai wandered through the forest in search of him,
Hulkmaru leapt down, warning "Smash," but Sai assured him that she was
not there to fight. Although he initially refused to listen to her
proposition, when his son came out and expressed his hunger, Hulkmaru
explained that the Oni did not eat people or attack the villagers but
were just hungry: "People take Oni
tree, so Oni have to take people food." Sai told Hulkmaru that
if he helped them against Orichi, she promised that the villagers would
honor the Oni's boundaries.
(Demon Days: X-Men#1 (fb) - BTS) - Hulkmaru agreed to this.
(Demon Days: X-Men#1 - BTS) - After Tsuki had her people light up the fireworks around the temple, Juju found although Orichi had been pained, it had grown more powerful and to was able to resist her.
(Demon Days: X-Men#1) - Hulkmaru arrived and joined the fight, stopping Orichi from grabbing Tsuki and Logan.
Orichi mocked Hulkmaru as a pet to
humans and a disgrace to Yokai, but Hulkmaru grabbed Orichi's tongue
and dragged it away from the temple, after which Tsuki and Logan
attacked it further, although Logan lost his left eye in the assault.
As continued fireworks and attacks weakened Orichi, Hulkmaru kept Orichi's tongue wrapped around a pole, and after Sai further slashed Orichi, Hulkmaru leapt high into the air before flying down to smash Orichi.
Under the combined assault, Orichi apparently dissolved.
After Juju stated that Orichi would not come back, Hulkmaru told Sai, "No forget." Sai assured him that the humans would respect the Oni's lands, and the village's priests and/or warriors bowed and thanked "Oni-San."
(Demon Days: X-Men#1 (fb) - BTS) - The humans kept their promise.
For generations, humans stayed in their
villages and oni in their mountains, living in peace.
