PT Imps are nerf hard this event, you can almost one hit kill them every time.

'though I took the southern route, or "Hell Route" because I can barely do any scratch to the boss with Rei-Go ops member, since I only have Kasumi & Ashigara at battle ready status

Huh the artist made a mistake, "the day of Yamato's last journey" is Operation Ten-go, not Rei-go.

Rei-go is the operation undertook by a force of Ashigara, Ooyodo, Kasumi, Kiyoshimo, Asashimo and 3 unimplemented Tachibana-class DD, only Kiyoshimo was sunk.
