On the go and not going to try to add bubbles on my phone, but
Jintsuu's SFX are something like "sparkle sparkle" Naganami: "I want to become an adult." Not sure about Houshou's SFX, I could swear it's the one for a sink running but doesn't make sense here? Houshou's line is weird and one of those annoying lines to translate. It's something like "You were already able to do (well)!"
"Well" is in parens because it's me trying to cram よく in. But it basically is "You could do it!"
