Altsoba originates from Skypiea, as a member of the Shandian tribe, and resident trouble maker, him alongside his group of friends, often teased, pranked, and generally just annoyed, the older Shandian, especially the warriors, as Altsoba in particular, would challenge the strongest warrior in the village daily, and get beaten senseless, each time. For years he lived peacefully, to a degree, until a new Kami was elected, unlike the old Kami, a kindhearted young man, who wasn’t the greatest ruler, but was able to make peace between Skpieans and Shandians, this new Kami was a cruel old man, who wanted to see the Shandians wiped out, as he considered their manpower a threat.

One day, when Altsoba went to challenge the leader of the Shandian warriors once again, he found the warrior, bleeding out, with the new Kami standing over him, a jagged knife in hand, in a blind rage, Altsoba charged the Kami, and was nearly killed, before the warrior saved him, by shielding Altsoba from the dagger, at the cost of his own life, Altsoba at this point was crying, tears and snot pouring down his face, as he screamed and begged for the warrior to survive, but it was in vain, the warrior’s last act before he died, was to give Altsoba a tone dial, and tell him to run.

Altsoba did as he was told, and ran as fast as he could, the Kami, oddly enough, let him go. Altsoba almost made it to the village, but before he could, the White Berets descended upon him, restraining him, before knocking him out.

Altsoba woke up three days after that, just in time, as today was the day that Altsoba would get his sentence, from the new Kami, He was brought in front of all of Skypiea, Skypieans and Shandians alike watching him, with hate in their eyes, as the Kami announced, that Altsoba stabbed the Shandian warrior to death, in some blind fantasy, that by killing him, he’d become the new greatest warrior, Altsoba was horrified, and even more horrified, that everyone believed this monster’s lies, but there was nothing he could do, he whimpered, but refused to cry, as he heard the Kami give his sentence, Cloud Drifting, a fate worse than execution.

For two years, Altsoba drifted on a cloud, barely surviving, by catching Skypiean fish, eventually, he recalled the Tone Dial, and found it, the White Berets didn’t locate it, he was lucky in that regard at least, but it was time to hear what the great Warrior died for, even if Altsoba couldn’t even remember his name anymore.

The Tone Dial contained information that Altsoba never expected to hear, the Kami, if he was even still alive, intended to leave Skypiea, after forming a crew of the most dangerous Skypieans and Shandians alive, to travel to the supposedly massive Vearth below.

Altsoba did nothing but listen to the Tone Dial, for days, but there was nothing he could do, his will had been broken during the first month on this cloud, until one day, Altsoba realized his broken will, was his greatest asset, so he did what no man who still cherished life would do, he jumped off the cloud.

It felt like a dream, like he was falling endlessly, until he saw blue, and then green, and then he just felt pain, a lot of pain. He woke up a day later, drifting in the middle of the sea, somehow alive, he eventually washed ashore, and proceeded to throw the Tone Dial, the only thing that truly connected him to the Kami's stupid plan, into the ocean, and never looked back.
