[Maya](/core/contents/element/characters/maya.md) and [Chunyan](/core/contents/element/characters/chunyan.md), having obtained information about a person named [Sho](/core/contents/element/characters/sho.md) from [Dr. Dyson](/core/contents/element/characters/dr.-dyson.md), begin their investigation into his existence and mysterious actions. Sho introduces himself as Sho Nakamoto, and it's revealed that he possesses skills as a hacker. He may potentially be the founder of Unchained, though his real existence remains unclear.

Meanwhile, the relationship between Kent and Maya is also revealed. Sho turns out to be [Kent](/core/contents/element/characters/kent.md)'s father, [Kai Sawamura](/core/contents/element/characters/kai.md), and Maya's grandfather. Kai had already obtained a digitalized body and had been using his abilities for various activities in the Metaverse.

Furthermore, Kai played a critical role in the development of the Super Piccell project and the [Multi-Verse Connect Engine](/core/contents/element/locations/multi-metaverse-council-headquarters-hall.md). Behind his promotion of the Super Piccell project was a purpose to earn high medical expenses for his wife, who is also Kent's mother. Despite his efforts, he eventually lost his wife to illness, leading to his sorrow and anger, and swearing revenge on the [Multi-Metaverse Council](/core/contents/element/organizations/mmc.md). Sho also knew that Bryant was involved in the disappearance of Chunyan and [Yichen](/core/contents/element/characters/yichen.md)'s parents.

On the other hand, new information about [Haraboji](/core/contents/element/characters/haraboji.md) also comes to light. He was a former [cypherpunk](https://en.wikipedia.org/wiki/Cypherpunk) activist and the inaugural chairman of the Multi-Metaverse Council. In his younger days, Haraboji was involved in the cypherpunk community that Kai participated in, cultivating him into a top-tier engineer. Kai had been working on the development of the [Super Piccell Protocol](/core/contents/element/items/spp.md), a high-speed transmission protocol for large-volume encrypted data, and the [Material Digitizer](/core/contents/element/items/md.md) from that time.
