Bursting with life and energy, Jocelyn rolled her way into Suitachi's, grateful as ever for the automatic doors that would open without the need for her to dismount her Segway (well, she still ought to, but there was no sign telling her she had to, so she didn't). "Good afternoon, Mister Suitachi!" she announced, unfathomably chipper for someone who'd just woken up for a long PM shift of "mystery work" with an increasingly unreasonable boss.
"You're about to be just as giggly as Miss Jocelyn here!" Sleuth added, thankful her volume was still turned up. "Because Jocelyn is gifted with something you don't see a lot of in this stoic little store of yours!" She paused a moment to allow Suitachi to ponder if she was talking about massive breasts. "That's right: 30,000 zenny. All for little old me~"
"Now now, Miss Sleuth, you aren't that old," Jocelyn chuckled, though her navi didn't appreciate the humor. "Ooo, I can never make up my mind... You're better at it than I am! What are the nicest upgrades?" she inquired, crossing both gloves behind her back as she leaned over Suitachi's in a way that he might appreciate, though he would likely not appreciate her habit of buttoning her top button.
"With age comes wisdom, or so they say," Sleuth sighed. "Let's see... I could use a top-off with my final speed upgrade, which is fifteen-thousand, then then I'll polish up my buster with a homing shot for two-thousand, plus another six-thousand for three power ups... then another six-thousand six-hundred for eleven process upgrades. Assuming all of my rigorous finger-counting is correct, that adds up to twenty-nine thousand, six-hundred?"
"I'm sure it does!" Jocelyn giggled, placing all of the zenny on the counter. Suitachi would hopefully return the change.
*Speed Upgrade v3 for 15,000 zenny + Homing Shot Upgrade for 2,000 zenny + 6,000 for PowerUps v1, 2, and 3 + 6,600 for Process Upgrade v1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11 = Total 29,600z
30500z - 29,600z = 900 zenny remaining*
