Arasaka

In Genshin Impact, 'Arasaka' and 'Lanza' refer to different things. 'Arasaka' is not a character within the game. Instead, it's a reference to the megacorporation from Cyberpunk 2077 and appears as a popular theme for player-created mods in Genshin Impact. 'Lanza', on the other hand, specifically refers to 'Lansaka', a minor character encountered in the Sumeru region, primarily involved in World Quests like 'Cooking, the Flavour of Nature.' Lansaka is a friendly Aranara, a forest spirit. Therefore, in Genshin Impact, Arasaka is more of a player community reference, while Lansaka is a friendly NPC. They are not directly related to each other in the game's lore or narrative.
