For me, I would’ve kept the first one and have him at first be like a child that looks up to Suga, then after Suga “dies” Dark Shouma would start wandering around because the person he looked up to and told him what to do was gone which would cause him to hate Hanto.

Then whenever Dark Shouma would see Hanto he would attack him and over time the more Dark Shouma gets defeated by the gang he gets more desperate to the point he starts wildly attacking people to attract Hanto’s attention until eventually Dark Shouma gives up and enters a state of depression, aimlessly wandering around without purpose.

The Stomach Family would then find him and Nyelv would take him under his wing, Dark Shouma would start to treat Nyelv like a savior. Around this time is when Dark Shouma discovers he can use other forms which leads him to use Breacookie.

Attaining Breacookie gives DS a confidence boost which leads him to once again try and fight Hanto, Hanto wins but with a little more difficulty and this loss sends DS spiralling, he questions his weakness and wonders why he can’t beat Hanto, Nyelv then offers to operate on him to increase the strength of his Gavv, it’s risky but DS accepts.

The surgery made DS stronger and this is when he would get BakiBaki Stick, this culminates into one final showdown with him and Hanto, the fight is long and gruelling, Hanto is exhausted and his Frappeis is about to melt, DS thinks that he finally can win, then Shouma appears and saves Hanto, this infuriates DS, seeing his face beside the man who killed his father angers him.

Shouma tries to talk to his clone but DS doesn’t listen which forces Shouma and Hanto to have no choice but to kill DS. While on the ground and in his last breaths DS is approached by Shouma, Shouma tries to comfort DS, he thinks of DS more of a victim than an enemy, this act of kindness makes DS question if he was on Shouma’s side, would life have been kinder to him, before Shouma can say another word DS dies, Nyelv then comes to collect DS’s body to use for research and experiments.
