Sin & Punishment: Stage 2-3 (Normal)
Through Achi's help, Airan was able to defeat Brad and kill all of the remaining Armed Volunteers, as well as saving Saki from getting obliterated by their superweapon.
However, there was still a problem: Saki was still in his titanic Ruffian form, granted to him thanks to Achi's blood.
Achi had a plan, however, to change him back to normal, but it was not one that Airan entirely agreed with her on...
Saki had lost the humanity in his heart. Achi needed Airan to go inside of Saki's Ruffian body to revive his humanity, and as such revive his human form.
But to start that off, Achi needed Airan to shoot right at Saki's head to knock him out, and she just... couldn't...
Then... the last time she told Achi to shut up, it ended up being aimed towards a crying little boy...
Airan and this boy were in some kind of runaway train. She believed that Achi teleported her somewhere else, but why...?
Apparently, the two were somewhere in Long Island, in New York of the United States of America. Why did Achi bring Airan here...?!
For now, it was time to go through this train and fight more Ruffians...
----------
Several times, you will fight Mole Seemers as bosses. They don't have a lot of health, but they also don't give you a lot of time to kill them before they leave and deny you a Commander Bonus.
----
After fighting the first Ruffian wave, the boy shocked Airan again... suddenly calling her "Mommy"...
But HOW?! Airan's not a mother! Or... will she be...?!
----
Another boss along the way will be the Jelly Seemer. Just keep shooting it from where it's shoot at you.
Then prepare for even MORE Ruffian waves.
----
Airan was getting exhausted... She had never fought this many Ruffians in such little time before... Just what was going on here...?
And then on the news, Airan and the boy saw it... They were in 2017, 10 years into the future of where Airan came from.
Within that news, a visage... of Saki! Still in his massive Ruffian form! He was being hunted down by the US army!
So then... she finally asked for the boy's name...
His name is... Isa Amamiya. Which means... he's Saki's son!
And with him calling Airan "Mommy", this means that Achi sent Airan into a dark future where she and Saki have married!
Sure, maybe they were destined to get married and have children... but NOT in such a future where Ruffians have taken over the whole world! Not in a future where Saki is hunted as a monster!
This was all wrong... This needed to change, and Airan was ready to lead her future son to escape from this terrible fate!
----------
After fighting one more Mole Seemer, the final boss of Stage 2-3, and Stage 2 entirely, is the Birth Model.
This freaky thing of organic rocks is constantly trying to heal itself. Besides its slow yellow shots, it can also fire a purple laser randomly from one of the rocks, and a blue lightning pillar from the arm of another random rock.
Use the yellow shots and deflect them against the rock that the arm sprouted from to get rid of the arm for a few seconds. Attack the purple laser rocks the same way to not only get rid of them, but cause a 4-way explosion that will eliminate other rocks next by for faster damage.
But then when this Birth Model is nearly beaten, it takes on one more form where it uses a web to hang itself from the ceiling to swing against violently and lob bombs at you. If you want a better time at hitting it, shoot its webline down ASAP every time it spins one up.
I just BARELY managed to beat this boss with so little health and time left, especially since they play into each other.
----------
At the end of their trip, Airan and Isa... somehow managed to find Saki, in his normal human form, in one piece. Isa got to reunite with his "Papa".
The space they were all in now was from Achi's own vision. It was her doing that Saki would remain a gigantic monster that's hunted down by the planet.
But Saki, in his human form, didn't agree with this. He doesn't want to have a child with Airan in such a horrible future.
But Airan also thought otherwise. She DOES want to marry Saki someday, but live in a much better future where Isa and live happily and lovingly with his parents and Saki is no longer a monster...
So then, Airan shot Saki in the head, breaking Achi's vision of that future against her and hopefully bringing Saki back to normal in real life.
----
Achi was using Isa to manipulate Airan's feelings...
Achi was trying to work up Saki's powers through her blood to help her defeat something far greater than the Ruffians and the Volunteers combined.
This plot already destroyed Tokyo, and will threaten the rest of the world, but Achi promised that a new world will be made from this global war she's been trying to start, and then end, this whole time...
Rather than actually changing Saki back to normal, she needed him to be EVEN STRONGER! To be her final weapon!
But then... Saki with Airan... escaped...
Their REAL enemy was in front of them this whole time...
