Ultraman, Vol. 4: Volume 4

Decades ago, a being known as the Giant of Light joined together with Shin Hayata of the Science Special Search Party to save Earth from an invasion of terrifying monsters called Kaiju. Now, many years later, those dark days are fading into memory, and the world is at peace. But in the shadows a new threat is growing, a danger that can only be faced by a new kind of hero--a new kind of ULTRAMAN...

Earth's alien enemies are brutal and unforgiving, but Shinjiro is having a tough time coming to terms with the way Dan Moroboshi kills them without hesitation. Perhaps just as disturbing is the new Ultraman suit Moroboshi is wearing. While Shinjiro deals with this, a secret plan to awaken Shinjiro's Ultraman Factor is set in motion, and singer Rena Sayama's life is in danger...
