May I ask for an explanation or scan regarding this adaptation? because in my opinion, the adapt here is too exaggerated in the concept type class ..., and also, maybe you should here explain the adapt mechanism here, before Shizuku fully adapts here, she will immediately lose to Ikki's ability, why? because here it is superior to Ikki's attack which is above Causality in general (Bypass Acausality 4), Ikki's Fear Manipulation problem, Resistance to Death Manipulation is not enough for Ikki, but also Resistance to Fear which has several kinds of abilities, Meanwhile Desperados has Resistance- Immune to Conceptual Manipulation Type 2 btw(Stella Vermillion).
The explanation is just that in Arifureta people with can do crazy things with will power, though if you want scans I can post the ones already in her profile, here is the natural adaptation of her body:
And
here is a scan about her will resisting things law and conceptual manip type 2,
then here is a scan of Tio, the character that showed a comparable will to her in the previous scan, resisting concept magic which currently is becoming type 1 (the reason to why the Tio took a time was because she not only was resisting it but was transforming said power on her own to get a big power up)
The fear manip is completely useless considering how she can resist Hajime fear and madness manip which normally can not only affect machines but that in the previous key was so great that it become concept magic. Her resistanse come from apparitions like Yato no Kami,
which authority is a curse that destroys anyone who sees its form along with their family, apparitions are abstracts beings born from the conception through the worlds so their abilitites are conceptual in nature.
Unless a character lack concept (NEP aspect 2) so there I highly doubt she is immune to conceptual manip, to begin with neither Desperados nor Stella have listed any resistance to conceptual manip type 2 so don't know why you say that.
And as for adapting, from what I'm seeing she adapts to mana, which would equalise to magic in this case. Desperado shit is completely separate, it uses no magic at all it has nothing to do with it.
He would get hit because there are a hundred of such attacks with big aoe, the swords can also use gravity manip to attract things so she can easily pull him to the attacks,
she also have the skill to hit him as if nothing, specially with her No Tempo that null Trackless but I'm not gonna talk about skill here, more so when I'm busy with other things.
Nop, the characteristic of the unique energy of her body let her adapt to any unique energy (mana and magic for example were just a energy to which she adapted at the beginning of the novel). In Arifureta exist many different unique energies and powers, and their abilitites (including their resistance development do to force of will) still work normally against such things, for example the apparitions (which use conception as their power and aren't related at all to magic), divine spirits (which use spirit energy as their power and aren't related at all to magic), dark beings and those with blessing arts (which use blessing power and its antithesis, which although could look similar in some aspects to magic is stated to be completely different), etc.
