"The Fifth Demon God a Man Known as the Grim Reaper" (第５魔神。死神と呼ばれた男。 Dai-go Majin. Shinigami to Yoba Reta Otoko.) is the seventh chapter of Super Dragon Ball Heroes: Dark Demon Realm Mission!.
Shroom calls upon a Grim Reaper Soldier who appears from a portal in the ground and attacks Xeno Janemba. When Xeno Janemba attempts to retaliate with a kick, the soldier grabs a hold of his leg. Shroom then uses his Scythe to cut through the two of them in one swipe. Xeno Janemba however re-materialises gaining more power than before due to the Dark Dragon Ball.
This time, Shroom goes in for the attack personally and while at first Xeno Janemba is able to put up a decent fight he is ultimately cut in half again and the Dark Dragon Ball falls to the ground.
However, before Towa can retrieve the ball, Xeno Goku, Xeno Vegeta and Chamel show up in front of them. Chamel vows to destroy Towa and Shroom with Towa commenting that Chamel had betrayed them after all. Chamel tells Xeno Goku and Xeno Vegeta to attack Shroom while he deals with Towa and they all begin to battle.
Suddenly the Dark Demon God Xeno Majin Buu who still has the Three-Star Dark Dragon Ball merged appears and using a detached part of his body absorbs Xeno Janemba to undergo another transformation.
Meanwhile, Xeno Goku and Xeno Vegeta struggle against Shroom as they have little strength after having their souls mowed, one of Shroom's special abilities.
Meanwhile, at the Time Nest, Chronoa having recovered from her injuries and having a good rest claims that she now has the energy back that is needed to summon a new helper.
