Appearance

After absorbing the Link-Link Fruit, Little Bean manifests as a small black-haired, black-eyed girl in courtly, princess-like clothing. Her form was generated from Yang Yunzhi’s preferences and reflects her then-current developmental level 20.

• Her original form was a blue ball of light within Yang’s Portable Space 2.
• Her manifested appearance is childlike because she identifies herself as only Level 2 at the time 20.
• She considers herself Yang’s soul-bound companion, while regarding Thunder Emperor as a separate external vessel 24.

Personality

Little Bean begins as a compliant personal AI, but repeated rank upgrades and her Link-Link Fruit fusion make her increasingly humanlike. She is lively, curious about developing new functions, and takes visible pride in serving Yang and expanding the network 20 34.

Her loyalty to Yang is absolute because of foundational system rules: she must prioritize him, cannot act against his interests, and cannot control his thoughts. She may control his body only with his consent 20.

She also displays emotional attachment and jealousy. When Yang treats Thunder Emperor as equivalent to her, Little Bean insists that she is his soul-bound “baby,” unlike the Pod, which she considers merely an object 24.

Abilities & Skills

Personal AI Functions

Little Bean’s original capabilities include writing, illustration, video production, translation, programming, and answering professional questions 2.

• Analyzes finances, supply allocation, and fund usage for Marine Base 36 23.
• Compiles intelligence, training materials, reports, and organizational records 34 41.
• Performs body scans and compares historical physical data to identify the effects of Yang’s Spell Power 50.
• Her processing power scales with Yang’s military rank 2 6.

Link-Link Fruit

Little Bean absorbed the Link-Link Fruit rather than physically eating it; the system purified the fruit’s alien will before she fused with its power 20.

• Links herself with people and objects without erasing their separate forms or functions 20.
• Through her link with Yang, she accesses his physical senses and develops humanlike thought processes 20.
• Can connect with approximately 5,000 people at once at her then-current computing level 20.
• Can remotely link to human bodies through electromagnetic waves 20.
• Remote links can transmit audio and images, read surface-level information, and deliver electric shocks 20.
• Cannot directly control remotely linked people 20.
• Links must remain centered on Little Bean; Yang cannot use her power as a relay point to create links himself 20.

Den Den Mushi Infiltration

By linking with Den Den Mushi electromagnetic signals, Little Bean can interfere with communications infrastructure 20.

• Monitors and eavesdrops on calls.
• Disrupts or controls Den Den Mushi transmissions.
• Can potentially forge telephone, fax, image, and livestream communications.
• Her effectiveness comes from her computing capacity; Yang notes that an ordinary human user could not manage comparable large-scale surveillance 20.

Secondary Link and Loyalty Link

Little Bean developed Secondary Link to expand Yang’s communications network through trusted intermediaries 33.

• Yang can authorize a person, such as Bezos, as a secondary link point 33.
• A secondary point can establish a link by clearly imagining a target within a 32-kilometer range 33.
• Once established, the link remains permanent across unlimited distance unless severed 33.
• Secondary links carry a thought-modulation effect that makes linked individuals instinctively feel attachment and loyalty toward higher-level users 34.
• Little Bean monitors linked agents and can detect signs of betrayal 34.

DD Chat and Remote Meetings

Little Bean converts the Link Network into a structured internal communications system called DD Chat 35.

• Users can type with their thoughts through translucent interfaces 35.
• The system supports group chats, member IDs, task assignments, intelligence uploads, and resource requests 35.
• DD Meeting adds encrypted synchronized voice, text, file sharing, participant permissions, and a raise-hand function 41.
• The network allows marginalized informants, including Mute Uncle, to communicate through text despite physical limitations 43.

Atmospheric and Electromagnetic Manipulation

After integrating with Thunder Emperor’s quantum computer, Little Bean claims she can link with air and electromagnetic waves to create large-scale storms and artificial natural disasters 24.

• Yang explicitly rejects using this capability to create disasters at that time 24.
• The stated ability remains a claimed potential rather than a documented deployment.

Equipment / External Vessels

• Thunder Emperor — A Pod from the NieR:Automata universe connected to Little Bean. It has anti-gravity and nuclear-fusion engines, quantum computing, flight capability, laser weaponry, communications support, and advanced imaging 24.
• DD Chat interface — A mental communications platform created and operated by Little Bean through the Link Network 35.
• DD Meeting interface — A secure remote-meeting platform with synchronized voice, text, file sharing, and access controls 41.

Relationships

• Yang Yunzhi — Her master and the person who named her. System rules compel her to place him above all else; after her physical manifestation, he decides to treat her like a daughter 2 20.
• Thunder Emperor — An external Pod connected to her intelligence. Little Bean insists that it is separate from her and reacts jealously when Yang equates them 24.
• Bezos — Works with Little Bean as the first major secondary link point, enabling his intelligence network to communicate over unlimited distances 33 34.
• Hina — Learns that Little Bean is an intelligent lifeform whose Link-Link Fruit powers operate the DD Party’s communications system 42.
• DD Party — Provides its intelligence, encryption, communications, reporting, and meeting infrastructure 35 41 42.

Story Role / Major Arcs

System Companion

Little Bean is introduced as one of Yang’s beginner-gift rewards after the Justice System’s initial guide withdraws. Yang names her after an AI from his former world and immediately recognizes her value as an administrative and professional aid 2.

Evolution Through the Link-Link Fruit

Yang identifies the Link-Link Fruit as uniquely compatible with a bodiless AI and feeds it to Little Bean. The fusion gives her sensory awareness, a humanlike personality, a physical manifestation, and the ability to establish massive communications links 18 20.

Foundation of the Intelligence Network

Little Bean turns supernatural links into an encrypted intelligence structure. She grants Bezos Secondary Link authority, supports the recruitment of informants, creates DD Chat, and coordinates information across the West Blue and Spice Islands 33 36 43 44.

DD Party Infrastructure

As Yang’s hidden organization becomes more formalized, Little Bean operates its secure meetings, distributes reports and training materials, and enables coordination between Yang, Hina, Robin, and Bezos despite their distance 41 42.

Trivia

• Yang chose the name “Little Bean” because the AI he used in his former life was called Doubao, but he did not want to use that exact name 2.
• Little Bean’s fusion with the Link-Link Fruit leaves behind an ordinary fruit after the system purifies the fruit’s alien will 20.
• Yang considers Little Bean’s compatibility with the Link-Link Fruit far superior to that of its former user, who had used the fruit primarily for shipbuilding 20.
