Thunder 3 manga volume 4 features story and art by Yuki Ikeda.

The Shibuya mission turns into a fierce battle—but after losing many of their comrades, Segami and the other remaining members of Rebellion turn to their secret weapon “Empoweral” to make their final stand against the super-powered aliens. And, little by little, the tide of battle seems to turn in their favor…Until a new menace rears its head from among the invaders' ranks! Elsewhere, the Small Three catch wind of the fighting in Shibuya from an internet broadcast and, faced with so much death and devastation, are forced to make a choice: do they continue to search for Futaba, or make for Shibuya at once?!
