Naofumi had no idea why this world kept screwing with him but he knew that Motoyasu wouldn't believe him if he tell him about the swap, Naofumi barely believed it himself, so had no choice but to pretend to be Malty, and he was sure every second of it would be torture.
"Yes, I'm fine Motoyasu, I was just... surprised you were so intimate with me" he said, trying to act like a shy maiden, he wasn't sure how the bitch acted with the spear hero but he was sure she was manipulating him.
"I see, you must still have nightmares about what that trash did to you" Motoyasu was rubbing his head as he got up, where a bump had appeared thanks to the small fall, but he quickly let go of it to adopt a more heroic pose, "Don't worry Myne, next time I see him, I'll make him pay for what he did to you and free Raphtalia and sweet little Filo!" as he said that last name his face went red as he close his eyes, probably imaging how he was going to add them to his harem.
Naofumi grunted at this, he didn't remember this guy was so obsessed with getting more girls to follow him, but he knew he had to dissimulate his disgust, offering Motoyasu the best smile he could and forced himself to not tell at him, "I'm glad to hear that Motoyasu, you're really... gallant"
Motoyasu just smiled at him, but as he was walking towards Naofumi, he picked a strange rock, "You sure this rock is useless? It seems pretty unique"
"I'm... not sure" Naofumi answered honestly, having no idea what these two were doing before the swap.
"That's shame" he rubbed his damaged head yet again, "Man that push was pretty rough, I wish this headache would go away" as he finished his sentence something odd happend, the bump on his head was slowly getting smaller and smaller until it disappeared, shocking both Naofumi and Motoyasu.
"Hey you see that? This stone is magic!" Motoyasu cheerfully yelled, taking a hand to his chin as he stroke it, thinking what else could the stone do, "This slimes barely got me any exp, I wish they would give more" as he said that a small slime was getting close to them, Motoyasu immediately attacked it to see if his wish had worked, a smile appearing on his face when he saw the experience he had won for that, "It's like I had just defeated thirty slimes, this stone is amazing! What else can it do?"
Naofumi now had a clear idea of what had caused the swap, of he could get his hand on the stone he could fix this mess but how could he take it from this idiot?
"I have a great idea" Motoyasu said as he smiled at him, "I wish everyone of my companions would love me, unconditionally" and as soon as he finished his sentence, the other two girls that were part of his party rushed up to him, throwing themselves at him, each one clinging to one of his arms.
"You're the best Motoyasu!" one of the girls shrieked, "Please marry me!"
"No, marry me! I love you more, Motoyasu!" the other girl shouted in response.
"This is great!" Motoyasu said, filled with joy as this stone would finally give him the harem he always wanted, but he quickly looked at Naofumi, "What about you Myne, do you love me?"
Naofumi dreaded he would start feeling something for that idiot but surprisingly he still feel hatred towards him, making him leave a sigh of relief until he realise Motoyasu was looking at him, if he noticed something weird he could make another wish, one that would affect him, so Naofumi swallowed his pride and clumsily walked up to him thanks to Malty's boots, getting his arms behind the spear hero and hugging him, "I always loved you, my beloved Spear Hero!" he said, wanting to throw up as he finished, yo make it worse, he could feel his new breast pressed against Motoyasu, making him feel an odd sensation and being another reminder of his situation, Naofumi just hoped he could steal the stone and swap back before Motoyasu wishes something stupid.

"I told yo to get lost demi human!" Malty shouted as she was trying to get away from Raphtalia and Filo, who where extremely worried from their master's sudden change if attitude.
"Master Naofumi, what happened? Why are you so angry" Raphtalia asked, full of concern, placing a hand on Malty's arm which she proceeded to push away.
"I think master finally got tired of Raphtalia, so that means he's all mine!" Fill cheered as she hugged Malty, who proceeded to push her to the ground, making the girl yelp, not expecting that from her kind master.
"Don't touch, stupid bird!" Malty screamed, "Now stay here, I have to-" before she could finish, she felt something odd, age was suddenly overwhelming by an intense desire to be with Motoyasu, not wanting to leave him with the shield demon, making her quickly run towards the dungeon.
"Master Naofumi? Where are you going?" asked Raphtalia as she helped Fill back on her feet, worried by 'his' erratic behaviour.
"I have to find my beloved Motoyasu!" Malty shrieked as she ran away, leaving Naofumi's companions utterly confused.
-----
"I'm so glad you found this stone Myne, I feel unstoppable with it" Motoyasu said as he kept enjoying the embrace of two girl and swapped and confused man.
"Motoyasu!" a voice suddenly took him out of blissful trance, looking at the dungeon's entrance he saw an exhausted looking "Naofumi", who was running towards him, not giving him a chance to defend himself, making his beloved girl fell to the ground.
"Let me go!" Motoyasu yelled as he was being hugged by "Naofumi".
"My beloved Spear Hero! I finally found you!" Malty said as she kept sweetly embracing him, much to his displeasure.
"Beloved? What are you talking about?!" Motoyasu desperately looked at Naofumi, "Myne, help me! Get him off me!"
Naofumi was shocked by the scene in front of him, his own body hugging and trying to kiss that stupid Motoyasu, he wanted to puke just seeing it, assuming that backstabbing bitch was inside his body and had been affected by Motoyasu's wish, so he decided to take advantage of the situation and search for the stone before someone else could pick it up.
