450 Betrothal (1/2)

When the spirit descended upon her, basically, when Natsuya became his Spirit-branded Retainer, nothing unusual happened to her at all. Her behavior was only affected after they finished the Spirit-branded Alliance contract, so simply contracting with Rana or Hitaka to become his Spirit-branded Retainer shouldn't affect them.

But, without actually trying, there was no way to be certain. If Rana or Hitaka really started behaving like Natsuya just earlier…

Seiji's imagination ran wild for a moment as he imagined the possible scenes. Then, he managed to stop his wild fantasies as he smiled wryly.

'Why on earth would my Mana have such a strange effect? System, it wouldn't be your doing, would it?'

As always, there was no response at all from his system. Seiji could only imagine a fairy representing his system again so that he could continuously poke it in his mind.

Then, he continued checking out his system. Underneath [Natsuya Yoruhana] in his system was an option called [Mana Exchange].

According to his system, [Mana Exchange] would have the effect of increasing both their power levels by at most ”four levels.” It additionally explained that the level of increase would be affected by Natsuya's favorability rating towards him as well as connectivity rating.

Basically, as long as the student council president got along well with him, they would be able to reach the strongest stage of [Mana Exchange], level four! Both their power levels would raise by a noticeable amount, while the time that [Mana Exchange] would last depended on how long the two of them were willing to carry the burden on their Spiritual Power.

They didn't even need to cultivate in order to improve their power levels for this… was this a type of reward to try getting Natsuya's favorability rating and connectivity rating to him as high as possible?

”Let's try [Mana Exchange] tomorrow and see how much it can strengthen us by.”

[Mana Exchange]… Seiji could only helplessly hope to himself that the same thing wouldn't happen to Natsuya again.

Natsuya suddenly felt that same feeling of ”comfort” from earlier.

She was currently taking a bath, completely relaxed and not on guard at all. She just happened to be reminiscing about how she felt earlier when the same feeling suddenly washed over her again!

”Wahhh~~”

The president did her best to cover her mouth as she shrank her body into a ball in her bath as her elegant body trembled and her legs tensed up with her face speedily turning red.

”Why has this feeling returned… Ahh~~~”

At any rate, it was really comfortable! Incredibly comfortable!! Too comfortable!!!

She wasn't sure if it was because she was currently taking a hot bath, but the sensation was even stronger than the first time. She did her very best to cover her mouth and barely managed to restrain herself from shouting.

When receiving such a sensation, she was completely unable to think anymore, and could only immerse herself in it and wait for it to pass. It was as if she was a sailboat caught in a windstorm, constantly buffeted and tossed about as she could only bear with it until it passed…

”Whew…”

Natsuya heaved a sigh of relief when the feeling of ecstasy finally subsided.

Currently, her face was completely red and her body felt drained of energy. Her vision was hazy as her eyes were teary, and she was collapsed by the side of her bathtub in an incredibly sexy manner.

”My power increased again… his Mana was actually able to improve my power twice in succession?”

Natsuya noticed the increase in her own power level. She felt that her strange sensations were connected to the increase in her own power.

Her power was already increased once already when they made the Spirit-branded Alliance, and now it was increased once again!?

Forget about whether or not there would be a third time, having her power enhanced twice was already something out of the norm.

This was… truly amazing.

Once again, she marveled at how astonishing Seiji was.

She decided to stop thinking too much about why this was as she wouldn't be able to come up with an answer. The current important part was, would he be able to withstand the burden of contracting with Rana and Hitaka as well? If he could, would Rana and Hitaka also be similarly powered up?

Not only that, Natsuya felt a strange emotion when she thought about how Rana and Hitaka might experience the same sensation as her.

It was as if she was watching her boyfriend do something with other girls… no, no, this wasn't such a thing to begin with! Nor was Seiji her boyfriend yet!!!

The student council president's face burned up as she reflexively sunk her face into the bath water.

She didn't want to think about such things, but couldn't help it. The sensation of increasing in power through Seiji's Mana was just like doing it with him…

'Stop! No more thinking about this!! Nothing impure happened at all, stop running wild, imagination of mine!!'

However, emotions were always difficult to control, and Natsuya was unable to get rid of the strange emotion she was currently feeling.

'Hmph, it's all his fault! Why is his power so… perverted!!'

Natsuya pouted slightly as she imagined Seiji's face and kept up an endless stream of complaints directed at him.

Right now, since she was still hiding out in her bath with her face flushed red, she definitely seemed like a girl experiencing youth who was missing her boyfriend.
