    On 15 November 1944, she departed Moji, Kitakyūshū destined for Miri, Borneo with fellow No.1-class auxiliary submarine chaser Cha-157, Type C escort ship CD-61, Type D escort ship CD-134, and minesweeper W-101, escorting convoy MI-27 consisting of four tankers (Awagawa Maru, Kyokuun Maru, Osakasan Maru, and Enkei Maru) and six transport/cargo ships (Edogawa Maru, Shoho Maru, Matsuura Maru, Seisho Maru, Koshu Maru, and Chinkai Maru). Enkei Maru and Kyokuun Maru developed mechanical problems and were forced to return to Moji. The convoy was running parallel to Convoy Hi-81 which had left Imari on 14 November 1944 destined for Formosa to benefit from air cover provided by HI-81's escort carrier Shin'yō which was carrying fourteen Nakajima B5N "Kate" torpedo bombers of the 931st Air Squadron, Saeki Naval Air Station. The two convoys converged together at times.
    On 17 November 1944, in the Yellow Sea off Cheju Island, MI-27 was spotted by the US submarines Sunfish and Peto which were operating in a wolfpack with Spadefish. Sunfish torpedoed and damaged both Edogawa Maru and Seisho Maru while Peto torpedoed and sank Osakasan Maru (killing 142). Nearby, Spadefish spotted Shin'yō of HI-81 and fired six torpedoes four of which hit causing the carrier to burst into flames and sink (killing 1,130). W-101 and CD-61 were disattached from MI-27 to pick up survivors. On 18 November 1944, Sunfish torpedoed and sank the damaged Seisho Maru (killing 448) and the damaged Edogawa Maru (killing 2,083); while Peto torpedoed and sank Chinkai Maru (killing 39). After losing four of the eight ships being escorted, the remainder of convoy MI-27 arrived at Sijiao Island on 19 November 1944.
