Hana gave Seiji the information on several Spirit Worlds and their locations, including the Spirit Worlds' consistency, the Spiritual Creatures contained within, as well as the general environments of those Spirt Worlds, the precious resources already discovered within, and the factions that he might meet in those Spirit Worlds.
All this information was doubtlessly valuable. Seiji passionately expressed his thanks, but his younger sister felt only disgust.
'Ahh, my tsundere younger sister is so cute~!'
Seiji was quite grateful as he mulled over which Spirit World location he should try going to based on the information Hana provided to him. Finally, he decided upon...
Nagawa Amusement Park!
That was the place where he met with Iroha Hasegawa and Naoki Hasegawa.
The main reason was that the Spirit World located here had a relatively high amount of "silver fruits."
