As two forest-dwelling sisters named Aqua and Eris bring ruin upon any intruding adventurers, Makoto celebrates the anniversary of the establishment of the Demiplane by meeting one-one-one with its denizens, from Akina the Alke (who has learned to perfectly mimic humans) to Liddy the Lizardman (who still looks like a lizardman). He also learns that when he pats the head of Tomoe’s fragment, she feels it too.
After a night of meeting, greeting his many admirers from Demiplane society, Makoto goes off on his own to practice his archery. Only both Tomoe and Mio suddenly feel his presence vanish, and find that by focusing on archery, he’s dying and being reborn over and over again. By being continually reborn, his mana continues to expand, as does the demiplane. Tomoe worries it will lead to the Goddess ordering his elimination.
Thus Makoto must learn to mask his enormous mana even more, both with his own magic and the gear the dwarves make for him. In the meantime, he still has a business to get up and running, which means returning to Tsige, where he helps a demihuman in need who also happens to look a bit like him.
A prostitute witnesses his kindness and decides to reward him with a night of fun, but a jealous Tomoe and Mio come out of nowhere to drag him off. He doesn’t want to tell them he loves them like family—as the ED indicates, they’re basically surrogate sisters. But by not saying so he creates a misunderstanding, and both women feel they need to make him a man immediately. Thankfully, he cools them off with an ice spell before they can assault him.
The next day Tomoe, and Mio in particular, regret how aggressive they were, and Makoto lays down some boundaries. That said, he’s happy to have Mio accompany him to Tinarak Forest to check out the ambrosia flowers that grow there. Makoto slips into the habit of his previous life in his world by offering to “hold handsies” with Mio, like he once did with his sister. Mio, obviously elated, takes his hand without hesitation.
Alas, she only gets to bask in the loveliness of that moment for 31 scant seconds before she and Makoto are rudely interrupted by two different parties: a trio of human adventurers led by the prostitute, and the pair of forest-dwelling sisters. Obviously Makoto and Mio are more more than a match for either, so it will really come down to how Makoto will de-escalate the situation and come to an understanding.
