A name-etymology seed: Oda layers a second divine-monkey signifier (Hanuman / Bajrangbali) onto the already monkey-coded Sun-God Nika identity, widening the “divine pattern” tracked by Sun God Identity and the Divine Pattern. Cross-link Luffy, Gomu Gomu no Mi .

Notes
Etymology pass DONE: kanji 猿神銃 “Monkey-God Gun” → Bajrangbali / Hanuman confirmed (Sanskrit Vajrāṅga; Oda Hanuman name-drop in Road to Laughtale Vol. 4). Catalogued on Gomu Gomu no Mi techniques table; Kaido’s countering flame techniques etymologized on Kaido. Confidence: high.
