Hikikomori Hero

[Passiflora C]

Looks self published, so no BW, and apparently the story is being written in tandem with another in-universe story, 'その無限の先へ'.
二ツ樹五輪 is the author of both.

For the first, it's the classic heroes and tights... at least on the surface. Yep. Classic heroes. Classic tights.
