[x] I have a strange relationship with training dummies and can summon them to aid me in battle.
Anything to not be the edgelord. Nobody likes the edgelord. Even now, half of the votes for that option are literal trolling, and nothing more.
And to those who claim we should tell Kurenai about it, because it's relevant to our job? Bullshit. Everyone in the village knows about it already, even if most don't speak about it, and that sure as hell includes the Jounin teacher assigned to us by the Hokage himself. She knows that we killed Tokei at the age of five. The only thing the edgy answer will tell her is that we've centred our life so much around that kill, and perhaps killing in general, that the moment someone asks us for something we consider interesting about ourselves, we immediately jump to that single thing, even if the situation and the material is very inappropriate. Considering how much attention our mother, Yui and indeed us, put on being polite, this says some very bad things about us. It doesn't mean we got over it. It means we still think about it all the time. That could be seen as us being a potential liability when killing comes up, because we still haven't got over it... or us being potentially unstable. In a society that has a long and time-honored tradition of geniuses going batshit crazy and massacring its people, and specifically in a village that has recently had Itachi slaughter his family, and has had Orochimaru stab it in the back a few years prior? We should pray they decide it's the former. Unfortunately, seeing as the answer implies that we see killing as interesting, and that we're probably known to barely sleep... Well. I won't hold my breath.
