Mitsuru and Rias were making short work of their area. The devil's wings and protective magic prevented anyone from getting close while Mitsuru defused each device in turn, eagerly pocketing them for later study. Her mind raced with possibility. If these contained even rudimentary technology from the invader's world, she could easily integrate it into her own systems and transform her ability to develop and simulate new equipment practically overnight. It could even pose a solution to the quandary she had faced in developing the permanent doorways that would remove the limit on the number of people who could come through from other worlds.
"We'd better hurry. I think the police are coming."
Mitsuru removed the next bomb and smuggled it into her bag. With that done, they spilled outwards onto the main avenue, carefully avoiding the areas where the police had deployed to protect the sites. Your explosive entrance a few blocks away had sent them scrambling to respond, leaving gaps for her and Rias to exploit.
"You have a big smile on your face, Mitsuru."
"I'm thinking of all the things I can do with these components. I can't wait to crack them open!"
"Just remember to disarm the explosives first, please."
Rias felt something. She wasn't certain of what it was – but years of learning how to fight had given her a sixth sense for this sort of thing. Thinking quickly, she tucked her wings close to her body and dived through the air with Mitsuru in her arms. The trajectory with which they were travelling a few seconds ago was struck by a precise beam of energy just moments later.
"W-What are you doing?" Mitsuru cried as her stomach did a somersault. The fact that they were under attack didn't occur to her. Rias covered as much of her body as possible, smushing Mitsuru's face deep into her DD bosom. Landing on the ground, Rias swivelled on her heel to face the attacker. It was Sundar – back to cause trouble again. Mitsuru ducked for cover, peering over the edge of a concrete tree planter.
"You again!" she cried.
Sundar sighed, "I had hoped that none of you would have dared interfere in our plan – but it seems that was too much to ask."
"Of course it is! I'm not going to let you kill someone with these things!" Mitsuru yelled back.
Sundar shrugged, "But I guess this is what they call a happy coincidence, huh? The Doctor's been running himself overtime trying to figure out how to stop you. But here you are, in the flesh! Meddling with my plan – with one of those damned devils by your side. I was already planning on killing you, but you just made my job so much easier."
Another blast of energy shot from his outstretched palm, only to be blocked by one of Rias' magical vigils. She scowled and stepped in front of Mitsuru, "Don't forget about me. I'm not going to make this easy for you."
"One devil isn't enough to beat me," Sundar boasted, "Even the ruin princess herself. I'm not a bumbling moron like some of my other compatriots."
Mitsuru yelled, "Rias, don't do anything reckless for my sake!"
Rias was already resolute in her decision though. The gauntlet had been thrown down, and she was faced with a difficult situation. On her honour as the future head of the Gremory clan, she couldn't simply abandon a friend like Mitsuru. She'd protect her or die trying, after all, Mitsuru was the one who introduced her to her fiancé. That was a debt that would take a lot of time to repay and Rias intended to fulfil every bit of their informal contract.
Even more than that – Mitsuru needed to live long enough to tell you how she really felt. There was nothing sadder to Rias than an unrequited love. A world where people only choose one partner was foreign to her, a social expectation that seemingly only existed to make people unhappy. Why not have multiple lovers if you were mature enough to handle it? It didn't make any sense.
