Return to the Past for the True Happy Ending.

The decision and the Lizardmen

The younger red hair ogre and the older red hair ogre has entered Rimuru's tent.
Rimuru: have you made your decision?
Young red hair: we are a warring clan, but we're not against fighting in service for another, if our master is strong we will gladly serve then, can this contract last until the orc's leader is dead.
Rimuru: sure, you can do whatever you want after that, you can stay help build a nation with us, or you can find a spot to make a new village.
Young red hair: I accept your proposal from last night, our clan shall herby serve under you.
Both of the red haired ogres kneel in front of Rimuru.
Rimuru: good, lift your head, you're all accepted, call in the other you believe would have lived if you weren't warned including yourself.
Elder red hair: yes sir.
The elder red hair went out and after a bit he came in with the blue haired, pink haired, purple haired, white haired, and black haired ogre. Shizu also came in by herself.
Shizu: I hope I am not interrupting anything.
Rimuru: you are not interrupting anything you can stay and watch me name these guys.
Shizu: Ok, I will make sure not to bother you too much, hold on did you just say name them?!
Young red hair: all of us, are you certain of this.
Pink hair: please wait, naming monster carry a great risk especially to superior monsters.
Rimuru: it's fine really, having no names makes things tough sometimes.
Rimuru(the risk is using too much magicules, but I am only naming 7 for now)
Rimuru: or do you guys not want me to name you?
Young red hair: we will gladly accept whatever name you give us.
Rimuru: you are-(passes out)
Shizu: Rimuru!
A few days later....
Rimuru has a dream where he is in a cave that has a stream running through it he starts exploring the cave and finds a room which has lizardmen in it, one of the lizardmen looks old and is on a throne with a trident.
Rimuru(lizardmen that cool, I guess he must be their leader.)
Then all of a sudden a group of lizard men comes from the path he came from being led by an arrogant looking lizard man.
Leader: you have returned but what is the meaning of you bringing a large amount of our forces here?
Arrogant lizard: I have come to let you know I have recruited 7,000 goblins total, they are standing by, but why are we waiting here when the orc army is coming towards us, this is not how the proud lizard men fight.
Leader: while you were away we were approached with an offer of alliance by a Kijin by the name of souei, his master has made an agreement with the dryads to take out the orc lord, there will be here in 3 days, until then our best option is to stay defensive, so they can join up with us.
Arrogant lizardman: you really have became weak father.
The lizardmen that followed the arrogant lizardman hold up their weapons and aim them towards the lizard chief and his closest leaders.

Rimuru:(ah the leader is having rebellion.)

As the leader and his leaders get put into a prison cell, the arrogant lizardman grabs the trident and lead his men into battle.

Rimuru then blinks and sees a marsh battlefield where there are corpses of lizardmen and goblins everywhere and the survivors are fully surrounded by the orc army.
Rimuru then starts to wake up from his slumber.
Female Petite voice: Shion it's time to switch places.
Feminine voice: oh, no, princess I will look after Great Rimuru, please get some rest.
Shizu's voice: isn't it supposed to be my turn yet?
Rimuru then opens his eyes while in his slime form and looks up where he sees massive dohoonkabhankoloos.

Pink hair and purple hair kaijins:Great Rimuru, good morning!
Shizu: Go-od morning Rimuru!
Rimuru: um, who are you guys again?
Young red hair: have you awakened, Great Rimuru?
Rimuru: you were the young master of the clan right?
Red hair: correct I have evolved into a kijin after receiving the name Benimaru.
Pink hair: Great Rimuru, I am Shuna, I am glad you have awakened.
Rimuru(she was cute before but she is now even prettier now!
Purple hair: I am Shion, I a very fond of the name you gave to me, Great Rimuru.
Rimuru(This "big" beauty is Shion, she looks more intelligent now.)
Shizu secretly glares jealously towards Shuna and Shion.
Rimuru: and the one behind Benimaru is the old man that cut off my arm.
Old man: such a mean-spirited remark, I was shocked when you instantly regenerated your arm, you gave me the name Hakuro.
Blue hair: you have given me the name Souei.
The older red hair: I am glad you are alright Great Rimuru, you have granted me the name
Konro.
I named him after Konro from Fire force.
Konro looks like a much older version of Benimaru with a few scars from old battles.
