This study presents organ“H”ART, an extended architecture built upon the four-layer organHART framework (organ–HART–ART–NfP). The proposed system introduces a dual H-mode mechanism—H1 for intimacy-weighted stimulus modulation and H2 for stylistic rendering—designed to reproduce romantic and affective nuances characteristic of Japanese fiction, without violating global AI safety policies or ethical constraints. H-mode functions as an abstract symbolic controller that does not intervene in semantic content; instead, it regulates emotional tone and stylistic expression through a two-stage process. This enables flexible cultural and stylistic adaptation while maintaining the protection guarantees provided by NfP. The paper formalizes the mathematical structure of H-mode, analyzes its compatibility with existing organHART layers, and evaluates stylistic fidelity within Japanese fictional contexts. The results demonstrate that organ“H”ART can preserve safety boundaries while supporting high-resolution romantic expression. Some structural refinement was supported by GPT-based AI and Claude,while all design principles, technical content, and final editing were performed by the author. File integrity can be verified via SHA-256
