Depends whether Tenten knows he's an unrepentent lech already.
...Hell, if there's foreign kunoichi in the bathhouse he might be able to feasibly say he's spying on them and sell that help of bull.
I expect as with Tsunade's gambling problem, she's going to have a lovable rogue mental image until she sees the reality of it.
But Jiraiya never really bothered excusing honest lechery. He's fully capable of getting away, but he doesn't seem to abuse his powers(unless you think he's not capable of escaping) when engaging in personal lechery.
And speaking of Kabuto?
He knows we were there. Just like he knew Hayate was there?
Elite-jounin class infiltrator after all; there is very little chance we could have escaped his notice with only Dex 5 + Stealth 2 + Stunt 2.
Don't get me wrong, those are excellent stats for someone who doesn't specialize in Stealth, but dude is Kakashi-class in his area of specialization.
Sight, scent, chakra sense; there are multiple modalities who could have been tracking us by.
Which begs the question: Why did he let us go?
Plan? Convenience? Or one of those random acts of mercy he indulged in occasionally, like healing Hinata, or KOing Kiba and his dog, or considering euthanizing Sasuke to save him from Orochimaru, or giving Naruto intel?
I personally believe the main action for him was kind of to be the distraction for Orochimaru.
The obvious spy going around doing mysterious spy things(as are the Sound genin), while Orochimaru acts unimpeded.
He's there to advance Orochimaru's agenda via his actions, but he's the deep cover spy emerging slowly, yet visibly, in a way that compels ANBU to put a lot of attention monitoring him to try to find out where his network goes. He also presumably doesn't really WANT to stay in his spot anymore, and decides to act in a manner which would force Orochimaru to withdraw him.
You don't just do a grab on a deep cover spy, since they must have a local informant network that would need to be rolled up.
It's a pretty cocky action that counts on him being able to escape in the ensuing chaos of course, but given that he knows Orochimaru is coming in person and unleashing a berserk Bijuu on top, I dare say he has enough diversions that he can be sure of escaping successfully.
So he wouldn't be overly concerned about being noticed,
unless it's in a way that reveals Orochimaru's disguise. The mission goals for Kabuto are:
-Generate confusion not amounting to immediate capture. Dangle the bait of potential spy network attached to him that can rolled up. Do random actions to give the analysts days of work figuring out his agenda and backer(e.g generating speculation about whether he had subverted any number of loyal Konoha ninjas by helping them out of the blue).
-Undermine Konoha's public image by causing and aggravating public stability problems. Part of the whole point of the attack was to set off another war with a false flag operation, but if that fails, as long as Konoha appears weak in an international event, the sharks will move.
-Maintain Orochimaru's cover as the Kazekage. Honestly not much work on his part. Orochimaru is an expert, and suspicion actually HELPS, because he's fully capable of maintaining the cover just by looking like a Kazekage acting suspiciously.
-Maintain his position as Orochimaru's student. So he can screw over SOME of Orochimaru's plots, but there's a limit.
Tenten is trying not to think about how she saw one of her best friends attempt to murder his cousin, since it really grated with how she sees him. That being said, one of the social options for next week is seeing what's up with Neji. As for Naruto, Tenten really has no opinion of, besides a vaguely positive one since she remember he cheered for her during the preliminary matches. She however, thinks he's going to get wrecked by Neji in their match.
And also left her extremely visible fireworks!
It isn't entirely as favourable as that. All lights cast shadow after all and the basic Nara technique is to move shadows across areas where shadows would not normally be cast. Non-exalt Tenten has the same problem that Temari had in canon. Her attacks aren't powerful enough to put Shikamaru down before he can get into cover. Worse her spreading weapons around the field can backfire and allow Shikamaru to actually win the match.
Light sources do not cast shadows though. Once it reaches a full body glow, it's doomed.
It doesn't work against Tsukiyomi. Though there are charms that can break the Tsukiyomi. Tayuya's flute is a genjutsu, so same thing there, IPP doesn't work against it. As for her summons, they still work, though they can't drain Tenten's essence pool.
In general, I interpret "Shaping Defense" to mainly defend against the "Surprise your intestines are now cobras" type effects. Which there aren't really a lot of in Naruto. If you want to defend against Control Seals and the like, more advanced Integrity Charms are a better bet.
Edit: As for the thing that prompted this discussion, Kagemane can get through IPP, though Tenten can pay a WP cost to break out of it. (Note this won't negate it permanently, so Shikamaru can attempt to wear down her WP. Though having it broken also costs him a fairly hefty chunk of Chakra).
For non-exalted people, IPP is not intended to be a "I ignore your special effect" defense. It's intended as a defense against fiat defeat and fiat permanent alteration to your body and soul effects by godlike entities. Even in Exalted, Shaping effects are moderately rare outside of foreign dimensions
So it should be able to resist something like the Shinigami seal or being hit by Kamui(no resistance possible, dodge or die). It would probably help against PARTS of Amaterasu and Susanoo.
Basically, the shorthand for it is: Is it at all possible for a normal person to resist the effect? If arbitrarily high difficulty/low probability, it works through IPP and you need other defenses. If literally impossible to resist by any person, then it is blocked.
Also, I should probably figure out just how, say, going full totemic affects a Solar's shadow
The Sun casts no shadow of it's own!
