チクサグル
Ainu「牽牛」
cikusakurmedium
Batchelor explicitly gives Chikusa-guru both as the herd-boy star and a ferryman, supporting the 牽牛 identification. Ota also lists Cikusakur but cites アイヌの星, so that entry is source-dependent. The ferryman sense is independently present in Batchelor; it does not prove a detailed etymology or the date of the name.
