Kagami drags Marinette to Tokyo to help the Stellars defeat a new supervillain, but Marinette soon realizes her friend has another, untold reason for this trip to Japan.

Set at an international school in Tokyo, 12 students discover they are guardians of the Stellar Matrix, a fractured ancient cosmic weapon. Under the leadership of Miki, Mayotte and Yu-Lu, these heroes must overcome personal differences and chaotic friendships to face formidable galactic villains such as the revenge-driven Moddler and the ominous force known as The Supreme.

Ever since his moth­er died in a fire, Ter­rence has seclud­ed him­self in an emo­tion­less world. He goes through his dai­ly teenag­er life apa­thet­i­cal­ly… with one excep­tion! The sim­ple sight of a flame plunges him into a world of fear, an awak­en ver­sion of his night­mares – for, every time he falls asleep, he help­less­ly relieves the trag­ic event, thus rekin­dling his pyro­pho­bia. Until that one night he can’t bear it any­more and stops run­ning away from the dev­il­ish flames. Lit­tle does he know that, by doing so, he over­came his great­est fear and became a Trav­el­er: a very spe­cial kind of Dream­er, able to explore Dream­land, the dimen­sion born from mankind’s dreams… and nightmares!
