Risa in her current form is a combat expert with multiple skills (Altered Carbon)

In occasions she is taken as slave and cloned and turned into multiple copies Autonomous Combat AIs. If taken as a slave then she must strive hard to break out of bondage!
The more skills and abilities and weapons the more dangers for her, since her clones as well gain her weapons and skills
Risa can synthesize and assemble multiple clones named Vanguards, who fight and defend her,she can clone others or her own self (Naruto)
Risa has mythic combat powers and weapons (7 Samurai, Alita)
Risa operates an array of powerful AI Network Systems to support her journeys
RPG is mostly individual travel-logs of her crossings and combats in different Realms, no linkage or purpose or design required between these Realms (Samurai Champaloo)

RPG's plants and edifices in occasions are turned into Autonomous Combat AIs to attack Risa or Risa's Vanguards
RPG's AI systems are programmable for the players to challenge themselves to learn how to build Cloud AI Systems
In Irish mythology Tír na nÓg (Irish pronunciation: [ˌtʲiːɾʲ n̪ˠə ˈn̪ˠoːɡ]; "Land of the Young") or Tír na hÓige ("Land of Youth") is one of the names for the Celtic Otherworld, or perhaps for a part of it. Tír na nÓg is best known from the tale of Oisín and Niamh.

In Celtic mythology, the Otherworld is the realm of the deities and possibly also the dead. Nevertheless, John Carey notes that it is not wholly accurate to describe all of them as gods in the medieval literature itself. He argues that the literary Túath Dé are sui generis, and suggests "immortals" might be a more neutral term.

Risa dwells in Tír na nÓg , not knowing whether she is dead or an immortal!
Note all machines and robots and drones and so on also dwell in Tír na nÓg since machines by nature are immortal given some maintenance and their designs and simulations are also immortals.
The Fomorians or Fomori (Old Irish: Fomóire, Modern Irish: Fomhóraigh / Fomóraigh) are a supernatural race in Irish mythology, who are often portrayed as hostile and monstrous beings. Originally they were said to come from under the sea or the earth. Later, they were portrayed as sea raiders and giants. They are enemies of Ireland's first settlers.

All enemies of Risa are Fomorians even her own clones!
