Platinum End, Vol. 6 continues where the previous tankobon left off and contains the next four chapters (16–19) of the on-going manga series.
Mirai Kakehashi is outnumbered with Kanade Uryu as Metropoliman and Sokotani Hajime. Instead of fighting the duo, Mirai Kakehashi steps into the mirror house and becomes trapped himself. The trap is devious one must be in constant motion or are killed. Therefore, Mirai Kakehashi and Nanato Mukaido picked up his daughter and wife respectively and take flight with their angel wings. They will continue to fly until they tire out, but hopefully before then they would find a way of escape.
Meanwhile Revel is having difficulty taking the mantle of Angel of Knowledge away from Baret. He tries to absorb as much knowledge he could, but he could retain it and realizes he could not replace Baret as Angel of Knowledge. Watching Saki Hanakago, his charge, keeping vigil for her comrades, who wants to be in the field, but can't, made him empathize with her to the point that he shed tears – a feat though impossible for angels. He was promoted to Angel of Emotions and gave his wing abilities Saki Hanakago – the first thing she did was to shoot a red arrow in Sakotani Hajime, made him fall in love with her, and to free her comrades within the trap.
Just as they are freed and Nanato Mukaido's family is safe, Kanade Uryu as Metropoliman returns (he left shortly after Mirai Kakehashi enter the trap) with three allies he had charmed with a red arrow. One of them is Bakumatsu Ryuji – a military agent who disappeared with a great number of weapons. Another is Kohinata Fuyuko a scientist that uses biological weapons to kill. The third is an unknown child reportedly with psychic powers, but wears an enormous mask of Donald Trump.
Prior to fighting the battle, Mirai Kakehashi stabs Saki Hanakago, who stabbed Nanato Mukaido, who stabs Mirari Kakehashi with red arrows simultaneously. It is a backup measure so that they would not be hit with a red arrow from Metropoliman or his associates and become succumb to the enemy. Sokotani Hajime was able to doge the firepower of Bakumatsu Ryuji and managed to sever his hand with his sword and Mirai Kakehashi used his white arrow on the biological weapon that Kohinata Fuyuko tried to use, by killing the living matter in the weapon.
Tsugumi Ohba has written another wonderful tankobon. I particularly liked how Revel was promoted – it was emotionally poignant and was depicted well. The battle was depicted well and I was somewhat glad that it was a one-on-one match, because if they went all out – following eight combatants would be difficult on the page. However, having it being a one-on-one match does not seem very realistic. As always, Takeshi Obata's art is simply amazing and accentuates the text rather well.
All in all, Platinum End, Vol. 6 is a wonderful continuation of the series and I can't wait to read more. I'm intrigued to find out how the story continues.
