Atsushi is in his final year secondary school, being in year 11 safe to say he is a ball of anxiety and worry not to mention the social stress of having to swap to a completely different school in year 10 after the bulling and uncomfortable nature of being in an all girls school as a trans man is damaging to say the least. he transferred to the same school his adoptive brother Dazai goes to even if he now attends the 6form.
a lab on the outskirts of the apartment in which he, his brother and sister all live in were experimenting with fusing animal dna. They made a break through creating a tiger/spider hybrid the creature was too powerful to be contained for long only a few notes and studies were conducted before it escaped and happened to find its way to Atsushi biting him and infecting him with some mutation of the two creatures ability's.
