Review Detail of Tinman in Highschool DxD: I have a Dimensional Travel System

Oy please stop dictating the author please let him write what he wants

Bro, DxD is a dangerous world (Despite what the power of Oppai might tell you) and any smart non suicidal Self Insert would definitely steal the thing that would let them infinitely double there power (To the limit they can handle) every 10 seconds pre Balance Breaker.

I rather steel Canis Lykaon.

some novels do it right though so if this is one of them i wont have any complaints.

Tobio is riskier to fight against than Issei

And fight Tobio and the Slash Dogs, I think not. Not to mention ending up on Grigori's radar

Why not, would you not do it if thrown in that world if possible. That would be most realistic way to move forward. DXD although looks fun in anime it is actually more difficult to survive than some cultivation worlds and it's even difficult to gain power as human. Plus issei is not really exposed to supernatural and not belong to any faction, and taking his gear won't cause any impact to his daily life.

like nascent kleidoscope

Only if it's in Murim worlds, because any medium Cultivation world leaves DxD in the dust in terms of power.

It's not about power level, It's about how difficult it is to get power in DXD. In cultivation novel you can still cultivate if you have even mediocre talent. But in DXD even if you are talented you will just be at the bottem ladder as human, Best case is reincarnated as lower demon or mid tier if you don't have a decent sacred gear (Which believe me are not as comman as anime shows). Even rias won't accept you unless you have exceptional power, I think among the devils only sona is someone who will be willing to take someone just for talent(Basically someone with no sacred gear). People are borned with fixed magic power in DXD which means you can not just cultivate and grow stronger, There is a reason reincarnated devils are marginalised and that too when they are just slaves. Issei and gang had a blast in anime because first, Sona and Rias were kind, Issei had boosted gear and he has plot armor.
