It takes a very long time to convince 21 that this is real, but Bulma doesn't really concern herself with whether this is reality or not. She sees a chance to be your partner, and she's going to take it come hell or high water. "Hm. So that's what happened..." 21 murmurs, "Interdimensional invaders. And you want our help fighting back against them?"
Bulma holds up a finger and raises a simple objection, "I can't fight."
You nod, "We know. The reason we chose you two is because you have incredible minds for technology and science. We'd like your assistance with breaking the mystery behind this CPU behind us. It's far too advanced for us to figure out alone."
Lala smiles and wraps her arm over your shoulders, "And in return, you get to spend time with hubby!"
Bulma frowns, "Damn it, guess I should have expected a hunk like you to have a few wives already."
"It's fine!" you insist, "Give it a few days and see if it's something you're interested in."
You know that Bulma is interested, the entire point behind summoning these versions is that they're going to immediately fall in love with you. But you still find yourself trying to be reasonable with them if they have reservations about the size of your increasingly silly harem. It's egotistical to assume, but these two are going to end up in the harem eventually no matter what you do.
"Oh, I don't mind! I'm more than pretty enough to get the attention of a man!" Bulma boasts, intentionally squeezing her arms together to try and emphasise her chest. "Soon, you won't be able to keep your hands off of me."
21 adjusts her glasses and coughs to try and draw attention back to the topic at hand, "Do you mind? I believe we have something else to focus on at the moment."
Mitsuru smiles, "So that means you'll agree to give us a hand?"
"I see no reason not to. If this device is of any interest, I'll pledge further assistance in return for information sharing on what we discover."
"Alright, just be careful with this stuff. These guys are way more advanced than any other organisation in the multiverse. We don't need anyone else ill-intentioned getting their grubby hands on these computer parts."
"I'll get back to you later, handsome!" Bulma giggles. She gathers around the workbench with Lala, 21 and Mitsuru to study what she's managed to do so far. Mitsuru had put together a rough schematic of what the device looks like on the inside. Bulma puts her amazing mechanical skills to use right away and drafts a second revision that makes things more precise and cleaner. You step back and sit down on the old couch to observe. You'll only get in the way if you try to offer anything to them.
It turns out that the combined brain power of the four of them is enough to crack the code in record time. Mitsuru is beside herself as 21 and Bulma easily blow past the problem that had stumped her mere minutes earlier. The CPU is dismantled bit by bit, with each component and material carefully studied using the analysis tools that Mitsuru has purchased with her toy line money. At first you thought that they wouldn't be a good team, but in reality, they're working so quickly that all four of them are taking on different jobs at the same time without even saying anything to each other.
You feel like a ghost. Bulma's flirtatious attitude dashed to the wind as her love of engineering and computing overrides her need to hit on the first handsome guy she sees. What kind of medium do you exist as in her world? A manga? TV show? All of the above? Or perhaps Mitsuru found a universe where she is simply very compatible with you. There's plenty of time to think about these things as they begin to chatter happily within the lab and share their findings.
"This alloy is superconductive," 21 explains to Lala, "It generates no electrical resistance at all, something we can only usually observe at freezing temperatures."
