Honkai Star Rail x Kamen Rider Build & Zi-O

Chapter 2: Astral Express and Build

Sento, March 7th, and Caelus immediately went down the corridor and headed to a large room where there was an elevator whose system seemed to be damaged.

Sento explained that the lift in the middle platform there would take them to the master control zone in the base area. They then decided to go to the elevator, but they saw at least 3 Reavers and 1 Baryon guarding the bridge leading to the elevator.

March 7th: "The Antimatter legion ! I think we should beat all of them."

Sento: "You seem to read my mind huh. Oh and Caelus, chances are you'll have to fight a lot, because it's possible that in the future you'll encounter lots of enemies that could be more dangerous than this, right ?"

Caelus: "Oh, I see. Okay..."

Sento, March 7th, and Caelus immediately charged towards the group of Antimatter Legion troops. Sento quickly changed into Build Rabbit Tank form.

Sento: "Henshin !"

"Hagane no Moonsault! RabbitTank! Yeaaah!"

March 7th readied his bow and Caelus readied his club. The three of them immediately attacked the group of Voidrangers, where Build kicked with his Tank leg at one of the Voidrangers, March shot at several Voidrangers, and Caelus hit his attack at Baryon who was behind.

Build: "Eat this !!"

Their fight lasted quite short because of help from Build.

March 7th: "Wow, the battle felt like it was over quickly. I think you really helped us, Mr. Kiryu."

Sento: "Ok, now we head to the elevator."

They all then immediately ran towards the elevator. When he got there, March stepped forward and tried to access the elevator key. However, an unexpected thing happened, where the control for access was broken.

Sento suspected that this must be the work of the Legion.

Sento: "Legion. The Legion must have broke it. They definitely don't want everyone on the bus to get out of here and this elevator is one of the main elevators for getting in and out of the station."

Caelus: "Can you fix it ?"

Sento: "Actually it is possible, but the security system for all elevators access control was all designed by Arlan. I'm just completing the term, so I think Arlan still needs help to improve it."

March 7th: "Wait... maybe Dan Heng can help us fix it. But too bad he's not here, he's just like a walking encyclopedia. He know a ton of complicated stuff... maybe even elevator reapir."

Then a familiar voice appeared suddenly from behind. He turned out to be Dan Heng.

Dan Heng: "I dont know that one."

March 7th: "(Shocked) Woaah !! Why are you here ?! And how did you get here before us ?"

Dan Heng: "I took another route to the upper level. Then I saw you guys from up there.(Looking towards Sento) Aren't you the reasearcher I just bumped into ? It turns out you're safe too."

March 7th: "Hey, Dan Heng... he is a genius named Sento Kiryu, one of the most influential researchers in the galaxy. He was also the one who saved me and Caelus from a horde of Antimatter Legion."

Sento: "Yo. So you're apparently a member of Astral Express, huh? I didn't expect that you were the one who hit me earlier."

Dan Heng: "(Confused and Shocked) Sento... Kiryu ?! Hmm, I kind of don't believe it. But if March said that I would believe it for now."
