Bond & Gift Guide: Babel Residents

The Kernel Hearts bond system explained: which Babel residents to befriend, how gifts work, what deeper bonds unlock, and the best early gift route through the tower inhabitants.

Quick Answer: How Does the Bond System Work?

Between expeditions, interact with the unique inhabitants of the tower and give them gifts to deepen your bond. Higher bond levels unlock bonus dialogue, chip discounts at the laboratory and character-flavoured bonuses — the social layer that makes the hub feel like humanity’s last living room rather than a menu. Gifts are cheap; ignoring the residents is the real cost.

Who to Befriend First

Prioritise the laboratory-adjacent residents first: their bond rewards bend the economy in your favour, and chip discounts compound across every future run. The bar owner — the Pink Wink Cupid’s Momo — anchors the social hub and her bond track is the community favourite for lore. Named residents like Nura round out the cast; the roster of bondable NPCs continues to be catalogued as players climb.

Talk to every resident after each expedition even without gifts — some bond progress is free conversation.

How Gifting Works

Gifts are items you collect during runs; each resident has tastes, and a well-chosen gift deepens the bond faster than a generic one. The loop is deliberately simple: run the tower, keep one interesting drop instead of selling it, hand it to the resident who wants it. Gift preference data is still being crowdsourced in the game’s first weeks — the FAQ page tracks open questions like these.

What Deeper Bonds Unlock

Confirmed reward tiers include bonus dialogue and lore at early levels, laboratory chip discounts at mid levels, and character-specific combat bonuses at the deepest bonds. Because discounts apply to every future craft, bond investment is effectively an economy upgrade — the fragment farming guide pairs well with a discount stack for maximum chip throughput.
