Doufu Mayoi 
Black Summoner: Volume 18 [EPUB ebook] 

Things are heating up in Lumiest as the exhibition match reaches its climax! But when fallen angels with a mysterious motive make their move, what will become of the event?

Both Dark Mel and Kelvin seem to be in danger as the fallen angels seem to have their sights set on the pair. The angels also seem more than willing to take hostages, so how will our heroes cope?

The enemy’s plans don’t just end with the exhibition match, though! What are they really after? What will be their next target? Either way, Kelvin’s definitely not going to be bored!
