[Matrixbeast]

Episodes 39 and 40.
We see the return of Jin, who survived the sucker punch, but was modified by Zaidos into a raging monster. However, he is able to overcome it and turn on him.
A notable part of this episode was Jin seeing the good through Ryou's actions, surprising considering he already saw the good in the world through his former partner...And he killed her...
Still though, while he never got his true final duel with Ryou, he went out Western style, fighting down foes before being taken down by a hail of bullets, knowing his death was coming.

40 also focused on the return of former characters, this time the 3 idiots. Challenging Shoji to a race, Zaidos reveals to have rigged the race, anticipating Kamikaze to fail like always and lined the finish line with bombs to kill Shouji as he crosses it.
Kamikaze (Actually neck and neck with Shoji) finds this out and, in a sense of honor for a duel between men, chooses to put his all into winning. The other 2 try to stop him, but they (Along with Zaidos) get caught in the explosion, dying rather tragically. One mech fight later, Shouji laments their loss at the sunset, declaring Kamikaze the winner.
...Until it's revealed that Hell didn't want them. They decide to denounce Gouma and choose to wander Earth, atoning for their sins.

I'm not surprised that these two episodes weren't as heavy considering the previous two. They were quite nice, giving us resolution and (Minor) redemption towards Jin, who ultimately wanted a fight between warriors, not as monster and senshi.
It was also nice to see the 3 idiots one more time. Though they were still up to their cheating ways, it was good to see that Kamikaze held enough honor to sacrifice himself, rather than kill Shouji through cheating.
