After being filled in on the situation, Shunsuke urges Yuu to stay with Ayumi at his research facility until his abilities disappear, as they put him at risk of being targeted. There, he learns that special abilities are the result of inhaling particles spread by a short-period comet called Charlotte. Later, Kumagami's aide Furuki is threatened into handing him over to a terrorist group, who force him into telling them everything he knows about ability users. Using this information, the terrorists kidnap Nao and hold her, Kumagami, and Furuki's family hostage in exchange for Yuu. Learning of this, Yuu goes to rescue them. Upon meeting up with the terrorists and ensuring the safety of Furuki's family, Yuu is attacked by another ability user, who slashes his eye, preventing him from time traveling. The pain of the wound triggers his collapse ability, which destroys the building. Although Yuu uses his telekinesis to protect himself and the other ability user, Kumagami is impaled after protecting Nao from the wreckage and dies as a result, devastating Shunsuke.
