Overview
Beyond Nexus Battles and exploration, Honkai: Nexus Anima includes a variety of side activities designed around interacting with Anima companions. These activities reinforce the game's casual, companion-focused tone. They're meant to be fun diversions, not grind-heavy obligations.
Known activities
Anima racing
Track races where Anima compete against each other. Details on the race mechanics (whether it's timing-based, stat-based, or a mix) haven't been fully shown, but the activity appears in beta footage as a recurring side event.

Balloon shooting
Players control an Anima to shoot down balloons. This is a straightforward arcade-style mini-game that tests accuracy and timing.
Demolition
Players use Anima to demolish buildings that are marked for destruction. The game frames these as sanctioned "rage rooms", you're not causing random property damage, you're clearing condemned structures. In practice, it's an excuse to smash things with your creatures, which is about as fun as it sounds.
Seesaw
Interactive play where the player and their Anima use a seesaw together. This falls into the "companion bonding" category. It's less about challenge and more about building the emotional connection between player and Anima that the game keeps emphasizing.

Water balloon fights
Players and Anima participate in water balloon fights. Another lighthearted activity that fits the game's seaside-town-on-summer-vacation energy.
Social features
Multiplayer socialization lets players interact with other players in the same world. Activities include petting and feeding Anima, attending social gatherings, and just hanging out in shared spaces. The social layer is designed to feel like a relaxed community hub rather than a competitive environment.
NPC interactions
Certain Anima have special abilities for interacting with NPCs. Vulberry, for example, can smear cake on NPCs to increase their favorability toward the player. These interactions are tied to the Anima's unique exploration skill rather than being a universal mechanic. You need the right Anima to trigger specific NPC reactions.
