Commando Comic #4690 'The Invisible Warrior' (2014)
 
When four Allied submarines were lost without trace in the same area of the Indian Ocean, the Top Brass believed it was the work of a new Japanese weapon, code-named Namurani. The remaining sub crews knew different -- the area was jinxed!

Lieutenant Dan Baxter, commanding the submarine HMS Bluefin, didn't know what to believe until he learned the story of the legendary Japanese Samurai Warlord, Tichibu, and his Spirit bodyguard, Namurani -- THE INVISIBLE WARRIOR!
